Lolz: Can't open read file mapping

[mixtro]

Hello everyone, every now and then I run into an issue with lolz where it complains that it can't open read file mapping



There isn't much of information regarding this error, so after hours of searching I found this thread
https://krinkels.org/threads/lolz.3649/page-3

In that thread two users were discussing about what the mapping process is and if unarc.dll does not have admin rights, lolz would complain.

The thing is, I set the setup.exe with admin rights and enabled windows 7 compatibility, but I still run into it.

I placed the setup in a virtual machine, and sandbox(Sandboxie), and the setup ran fine.

I tried running it with batch to unpack, and of course including the required cls dlls, yet still the same issue occurs.

I disabled windows defender, it still persists. I've replaced unarc.dll with several versions, it still persists. I've disabled smart screen, restarted the computer, it still persists.

What could be the problem? Anyone has any ideas?
