I am installing ST2 on a 64 bit windows 7 PC. The installation apperas to be nearly complete but I get this error message and can not continue.
Error 1721. There is a problem with this windows installer package. A program required for this install to complete could not run. Contact your support personnel or package vendor. Action: RgisterIconRegfile, location: ...\ThbIconHndlrTmp...
I didn't even notice the ST2. It was there and I was reading ST4 every time.
This is true. The initial release version of Solid Edge ST2 and 2D Drafting ST2 did not support Win 7. This was implemented and released in Solid Edge ST2, Maintenance Pack 2. Free 2D Draftring does not have maintenance packs. The initial release is what we have to live with until the next release.
