recently, My company need me to do something on application cache, and I read this article: http://www.codemag.com/Article/1112051, I followed his steps,but it cannot work by using vs2013, it will show you the right page, but when you press f12 in chrome, it will show some error:Application Cache Error event: "Failed to parse manifest localhost:xxxxx/Home/manifest", and actually app cache didn't work. but when I use vs2010 it works just fine! since vs2013 has a lot more files in the mvc project, I cannot figure out what's wrong. Now I need some vs2013 tools which are not included in vs2010, so I really need the vs2013 version of this app cache program. It's quite in a hurry, can anyone help me? thanks a lot!
Please follow these steps to see if it helps.
Step 1: Run Windows System File Checker("sfc /scannow")
It allows you to scan for file corruption and restore Windows system files such as DebuggerProxy.dll. If System File Checker finds a problem with DebuggerProxy.dll or other critical system file, it will attempt to replace the problematic files from DLL Cache (%WinDir%\System32\Dllcache). If the DebuggerProxy.dll file is not in the DLL Cache, or the DLL Cache is corrupted, you will be prompted to insert the Windows installation disc to recover the original files.
To run System File Checker:
1.Click the Start button.
2.Type "cmd" in the search box... DO NOT hit ENTER yet!
3.While holding CTRL-Shift on your keyboard, hit ENTER.
4.You will be prompted with a permission dialog box.
5.Click Yes.
6.A black box will open with a blinking cursor.
7.Type "sfc /scannow" and hit ENTER.
8.System File Checker will begin scanning for DebuggerProxy.dll and other system file problems (be patient - the system scan may take a while).
9.Follow the on-screen commands.
Step 2:Make sure your ISO installation file is correct.
You can download the ISO file from the website below.
http://www.microsoft.com/en-hk/download/details.aspx?id=40787]
Before you install it, I suggest you use this tool http://support.microsoft.com/kb/841290 to verify hash of the ISO. Any discrepancy would indicate that the file was corrupted. Here is a blog about how to use the tool.
The sha1 value of ISO is "E61419E51F42254EE07DECF628B85C9861286250".
Then try reinstall it.

I have developed a very simple electron app, which I then packaged using "electron-packager".
I zipped up the application and sent it to my client. When this client runs the application, he gets the "Windows protected your PC" window/warning with "Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.
App: AppName.exe
Publisher: Unknown publisher
Along with the "Run anyway" and "Don't run" buttons.
The app runs fine when the user clicks on "Run anyway", but understandably he would like to get rid of this warning (and at the very least show the actual Publisher).
I know about the code-signing certs, so there is no need to go there...
(IMPORTANT NOTE: I haven't asked him to look at the properties of the file to see if Security indicates "This file came from another computer and might be blocked to help protect this computer.". I am going to check that tomorrow and hopefully it just needs to be "Unblocked".)
What I am wondering is, why don't I get this same warning when I run the application on my PC? (We are both running Windows 10.) I have cranked my UAC all the way up to "Always Notify" and I have tried setting "Check apps and files" and "SmartScreen for Microsoft Edge" to "Warn" and even "Block". Still, the application always starts with NO errors or warnings. If I could at least reproduce what he is seeing, I would at least know if/when the code-signing works.
(To be clear, I'm not using an "installer". The client doesn't want one. And, as I said, this is a very SIMPLE application/utility. They want to be able to copy the zip file, unzip the contents and run the app..)
Any help is much appreciated!
Yes. The issue is, that when files are received from the internet, there is a download flag set. This is depending on certain conditions.
I've experienced, that files from local network addresses don't get this flag.
You can find the flag in the File Properties dialog.
When this flag is set, the SmartScreen scans the file and checks, if it can be trusted or not. This is depending on the reputation of the signature used to sign the executable.
Reputation for a certificate is established automatically. If you cannot wait, then you need to use an EV cert.
hope this works for you.
I use "electron-builder" to build my application and it exports a .exe file then I archive this file by WinRAR app and set it for download.
when the user downloads this file and extracts this file it automatically removes the downloaded flag from the .exe file and the user will not see the warning anymore this solution worked for me.
The solution to this is for the client to "unblock" the zip file before extracting. (Or, I suppose extract it, then unblock the exe....) To reproduce the problem, I just emailed it to myself. :)
I have installed Java 8 JDK and JRE, and when I type javac into cmd, everything seems fine. However, when I download a .jar, for example Optifine, I have no option to open with Java. The icon of the .jar is Internet Explorer. When I double-click on the Optifine .jar, I am brought to a "View and track your downloads" window, where I then get stuck in a "Save" and "Open" loop. What can I do to actually see Java as an option to open with? Sidenote: if anyone does reply, please use simpler coding language, as my knowledge only comes from hours of research on how to fix this problem.
I don't know which version of Windows you are using so I can provide detailed step by step guide. .jar files can be opened with Java and compression/decompression utilities. In general, you can change the default programs in control panel and associate .jar file with a specific program you want.
Note: As an irrelevant point in order to use Optifine.jar for Minecraft modding you do not need to open it.
I have the following error popping up when I try to run HP Fortify on my RAD 7.5 developer tool's project.
This is because it cannot find the SCA executable file.
Where do I need to point my developer to in the file directory for it to find the SCA?
I've figured it out.
First of all, when installing HP Fortify, I have to make sure to include the Eclipse Plugin. This I was already doing.
Second, after installation when running my first Scan, I have to locate the 'scourceanalyzer.exe' file on my computer.
In a standard installation to the C drive, the location of the file will be:
C:\Program Files\HP_Fortify\HP_Fortify_SCA_and_Apps_4.00\bin\sourceanalyzer.exe
You'll have to select "OK" when the second image I posted in this question pops up (the one that asks you if you want to locate the SCA Executable), and then you will have to navigate to the address of that file manually and select it.
It looks like you might need to re-install.
I'm having some kind of problem with my project that me and my friend is working on. When I try to open the project that I've been working on it gives me an error message saying that "one or more lines were too long and have been truncated" and thus I can't see my code or GUI. When my friend opens the project on his computer (The project is on dropbox so it's the same file) there's no problem at all. I've googled but couldn't find anything. I just did a repair of RAD Studio but no luck. We have 2 forms and a unit that we use, the unit and the mainform isn't working for me but the second form is no problem.
Thanks!
Make a copy of your project directory.
Search your harddisk for XXXX.pas and XXXX.dfm
Hopefully there will be some temperary files that match - like "mylostform.dfm.~1307~" . copy the newest to your project directory, and rename them to "mylostform.dfm" and "mylostform.pas".
Kind regards,

From the comments, you have Dropbox, and the Restore functionality is available, but using it would cost you a week's worth of work.
If I was in that situation, here's what I would do:
Copy the current file to somewhere else (My Documents, for example).
Use Dropbox Restore to get the old version that works.
Make a copy of this, because you're going to be modifying it
Ensure that you can open it in the IDE.
Use Beyond Compare to open the two files side-by-side. (If you don't have this, you really should!)
If they're completely different from each other, you have a serious problem. If not, you'll see the changes you've made. Start copying changes one at a time, and after each change, save and try to open it in the IDE.
At some point, you won't be able to. That's where your problem lies. Now you can fix it!
I have made a simple installer application in Delphi, nothing fancy. Basically I include files into the Exe, and then extract them to a user specified path.
I stumbled across a problem however, and I have noticed this works with ANY Windows Executable, it does not matter if it is an installer or not.
If an Exe is named, or contains the following words in the filename, "Setup", "Build", "Install" and maybe others, then.. whenever the Application is run and closed, Windows pops up a Product Compatibility Assistant dialog, saying the Application may not have installed correctly.
This is a problem, as even though the Files from my installer have actually extracted, and in my eyes the installer has done its job, Windows is complaining about it.
The only idea I have regarding this, is that Windows must check the filename of the Applications when executed, and in this case has identified it as an Installer. Windows must of then set a flag or something on the System, my Installer must then update this flag to say that the installation was a success?
Windows does not complain about this when debugging from the IDE, so it cannot be code related, it must be the OS - this only happens when launching the Application from Windows, not Delphi.
You can try this easily, either create an Application or rename one as Setup.exe, Run it and then close it - wait a few seconds and the Product Compatibility Assistant Dialog will show.
I don't know where to start investigating how to stop this dialog, or where a setting may be to tell Windows the Installer was completed correctly.
Appreciate your thoughts and solutions thanks.
If I recall correctly, this happens when your install app does not include an application manifest. When UAC was introduced, MS introduced a heuristic detection for installers and shows the UAC elevation dialog. The heuristic checks for names like setup.exe, install.exe. The simple solution is to include an application manifest. If it is an installer you probably want to use the requireAdministrator setting.
The feature is known as Installer Detection and is discussed here.
For what it is worth, I would always build an installer with a dedicated install tool like InnoSetup for example.
As David pointed out, MS uses some fuzzy logic to try to guess if the program is an installer. I wouldn't rely on this, as this is only for supporting legacy installer applications.
All new applications should have a manifest file, specifying whether it requires elevated privileges.
If an application has a manifest file that includes the requestedExecutionLevel directive, then Windows does not attempt Installer Detection.
Any program that is detected as an installer program but does not add a registry entry to the Add Remove Programs section of the registry (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall) will get the message "This program might not have installed correctly".
