Hi hmartin,
Instead of setting the environment variable to THINAPP_CACHE_DIR, set it to THINSTALL_CACHE_DIR and set the respective path as per your need. Also please go through the following information. I hope it is helpful to you.
CachePath-Sets the path to the cache directory that stores font files and stub executable files. You can use this parameter when you need to force the cache directory to reside on a different drive.
This parameter can contain macros, such as %Local AppData%, that expand before use. If the path is relative, ThinApp interprets the path relative to the directory where the package is stored.
For extra flexibility, you can use the THINSTALL_CACHE_DIR environment variable to override this parameter at runtime.
If neither the CachePath parameter nor the THINSTALL_CACHE_DIR environment variable is present, ThinApp uses a default locaation. The default location depends on the presence of a SandboxPath parameter in the Package.ini file. If the SandboxPath parameter exists and the path setting is relative, CachePath defaults to the same path.
If the SandboxPath setting exists and the path setting is absolute, CachePath defaults to %Local AppData%\Thinstall\Cache\Stubs.
For example, set the cache directory to C:\VirtCache:
CachePath=C:\VirtCache
With the package located in C:\VirtApps, the cache is set to C:\VirtApps\Cache:
CachePath=Cache
In a typical USB key scenario, you force the sandbox to the USB key. If the packages are stored in the \VirtApps subdirectory on the USB key, enter the following to force the cache directory to the USB key too:
CachePath=Sandbox
Thanks and Regards,
