Workaround is remove all early downloaded Autoinstaller versions from the Autoinstaller cache:
del C:\ParallelsInstaller\parallels_installer_Microsoft_*.*
Hi,
You fixed x32 vbscript.dll version. Please do the same for x64 one:
regsvr32 /U %windir%/system32/vbscript.dll
regsvr32 %windir%/system32/vbscript.dll
