Had the same crashing issue after upgrading and after some research I found this post that gives some details why the crashing is happening.
To fix the issue simply do the following;
Search for the file libcurl.dll in your VMware Workstation installation folder.
(I found 3 instances on my windows 8.1 machine)
C:\Program Files (x86)\VMware\VMware Workstation\x64
C:\Program Files (x86)|VMware\VMware Workstation
C:\Program Files (x86)\VMware\VMware Workstation\OVFTool
Make a copy of the files in the first 2 folders having a modified date of 28/04/2015
Replace with a copy of the file in the 3rd folder (\OVFTool) with modified date of 04/02/2015
Start up VMware Workstation
This fixes the issue and no uninstall or reinstall required, I've tested it and have not experienced any issue.
I take no credit for this as the issue was discovered in the post below which has more details on the exact issue.
