In the meantime of a Windchill migration from 9.1 to 11.0 we have to run on a same client different versions of Solidworks and WGM (respectively 2012 with 9.1-M070 and 2016 with 11.0 M01) but WGM 9.1 fails to launch after we have installed WGM 11.0.
I tend to suspect this relates to the having a common Cache and Root with 2 different versions of WGM.
Is this a known issue ? Are there known resolutions (environment variables for Cache and Root) ?
