A ThinApp which includes the .NET Framework generates the message: Event ID: 1101 ".NET Runtime Optimization Service (clr_optimization_version) - 1>Failed to compile:" (2018794)

  • 3 Ratings


When running a ThinApp application which includes the .NET Framework, it generates a message similar to:

Event ID: 1101 ".NET Runtime Optimization Service  (clr_optimization_v4.0.30319_32) - 1>Failed to compile:"


When capturing the .NET Framework, it is important to note that following the install of the Framework, the mscorsvw.exe process continues to perform operations related to the install for some time in the background. If you perform a postscan before these operations are completed, you may encounter issues when using the ThinApp.

To resolve this issue:

After installing the .NET Framework, run this command prior to performing the ThinApp postscan:

C:\WINDOWS\Microsoft.NET\Framework\version_number\ngen.exe executequeueditems

For example:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ngen.exe executequeueditems

Note: The version number (in this example, v2.0.50727) may differ. Check your installation for the exact version.

This forces the .NET Framework to fully complete the install.
