Operating System Version
Windows 10
Mu Version
1.1.0b2 - 1.2.0
Other Info
Tested several versions, the error appeared in versions: 1.2.0, 1.1.1, 1.1.0b3, 1.1.0b2. Most likely in the rest between these versions as well.
The error did not occur in versions: 1.0, 1.1.0-alpha.2.
I changed my Windows account name, thinking that the program only supports Latin characters in file paths. It didn't help.
A distinctive feature of the versions was the installers, which in successful attempts (1.0 and 1.1.0.0-alpha.2) gave the option to choose the installation path, and I installed the program in Program Files not on the system disk.
