I am trying to fix this error on solid 2017:
any idea on what to do?
It would seem from this error that you are missing some prerequisite installations for SOLIDWORKS. To fix this you can just install the prerequisite installations manually. To do this go to the SOLIDWORKS installation files, locate the "prereqs" subfolder, the run all the .EXE files in all the "VCRedist" folders. There are about 6 of them to run. Some are probably already installed so just repair those; some will not yet be installed (probably the 2005 versions). Once all of these Microsoft packages are installed on your computer the error should subside.
