If you have .net locally installed you can uncomment this line in your package.ini
; Enable this option to load .Net binaries from the system instead of the package on Windows 7 or above
;LoadDotNetFromSystem=Win7
As explained this makes your thinapp package use locally installed .net.
For the printing issue you could try to add the spool directory to your package and set it to merged (if the folder is not already present in your package):
- %SystemSystem(x64)%\spool
- %SystemSystem%\spool
You can also try to run splwow64.exe and spoolsv.exe outside the virtual enviroment by editing the following lines in your package.ini
- ChildProcessEnvironmentDefault=Virtual
- ChildProcessEnvironmentExceptions=splwow64.exe; spoolsv.exe
