Today I tried to install Shotcut, but faced the following problem. After launching the installation file, the NSIS error occurs. I tried both 64 and 32 bit versions, but the same thing happened.
I use Windows OS, 64 bit. Tried disabling the anti-virus, clearing cache, renaming the installer file name, but nothing helped.
Likely a corrupted download. Re download or try the portable version (no install necessary).
Thanks! Will try a portable version today.
