We have a ASP.net 2.0 web app with an installer which appears to hit an issue with .Net Framework 4.0. This has occurred on XP and Windows 7. Seems to happen every time.
During the installation, we call aspnet_regiis for various tasks such as encrypting the web.config. If .Net 4 is installed this throws the error:
aspnet_regiis.exe – .NET Framework Initialization Error
Unable to find a version of the runtime to run this application.
OK
Running the same commands from the commandline works correctly.
Anyone have any idea what is going on?
Thanks,
Davy
This issue was caused by aspnet_regiis.exe not dealing with short (8.3) filenames in this scenario. The fix was simply to always supply the full version of the path.
