Regarding error 1723:
This is most likely an issue with your Windows installation. You might want to try this:
hi timo, thx for the hint.
i just re-installed win 10 pro 32 bit including all available updates. installation went quite smoothly. i then executed the suggested tool. it didn't detect any issues. however the installation of rig manager 3.0.79 win 32 bit still crashes with exact the same error.
could this problem be related to the 32 bit installation routine? Did anybody confirm having successfully installed rm3 on win 10 32 bit?
