Recently, I got the error below when using the vSphere client.
I have only tested this solution on:
Repair your installation of Microsoft Visual J#® 2.0 Redistributable Package – Second Edition (x64)
The error went away after repair.
In trying to google the error some user have reported that uninstall the patch KB3147458 worked for them. I didn’t have the patch.
wusa.exe /uninstall /KB:3142024
Hope this helps.
