Interesting. So the very same version did not work by itself, but did as part of the full client package. Please also check, if there isn't a hung (running but no window) instance in Task Manager. During start it checks whether it needs elevate before starting, so depending on the contents of the folder this check may take longer or get stuck for some reason. That would also explain, why no crash has been logged in event log.

Assuming version 4.2.1, 64-bit, is that right? Can you try, if: it crashes with the other platform build? (i.e. if you use 64-bit, try 32-bit and vice versa) it crashes with recent older versions as well. Thank you.

Elurair already supports updating encrypted GRFs/GPFs (such as SecureGRF). Normally there is no added benefit to using Thor files other than compatibility with previous patcher, since Thor files are not encrypted as far as I know. 2022-01-22: - ZIP support complete - RAR is held until I'm bored enough to enter that source code abyss and figure out, how to make it open something other than files

Yes, this belongs to the same group of software as Thor Patcher. If there will be interest for that, there can be support for THOR files, too. Currently it can only work with GPF and RGZ.
