I uninstalled the program two times, restart pc... installed again, nothing, the same two errors. Like I said, I tried the previous installer and portable versions... nothing!
Also, I have MKVtoolnix on my pc..
So, how can be solved this problem? Can anybody help me, please?! Thank you.

Is your PC 32 bit or 64 bit? Did you download the correct version for your PC

I'm sorry, I forgot to mention... Windows 7 Ultimate x64, downloaded the corect version of the program...

That's the same operating system I'm running and it works without issue on my PC

It appears to be a Registry issue possibly from a previous virus or malware infection
