It's possible the files are conflicting with you system bit? For example, the files are x32 and your system is x64 or vice versa? I think I've had this problem before once. I'm going to reinstall the repack to see if I have the problem as well
@pkman unless you've solved the issue?
P.S.
https://trinitycore.atlassian.net/wiki/spaces/tc/pages/2130030/Application+Error+0xc000007b talks about how you need the proper corresponding dll files, "
This error usually happens when mixing 32 bit and 64 bit DLLs." You most likely have a mix of both 64 bit and 32 bit dll files. If you go into the "Required Software.rar" zip, and extract and install those software requirements, then grab the dlls you should be set.
