Revised 9/14/17 - May be caused by McAfee…
A small percentage of users are reporting that after a recent update, Rhino V5 64-bit will not start. Our original guess was this was caused by an unknown Windows update. Now there are indications that this may be caused by McAfee anti-virus instead.
Windows pops up a message like this about a damaged file:
The fix is pretty easy.
In Windows’ Control Panel
- Run the Programs and Feature tool
- Find "Rhinoceros V5 (64-bit) on the list
- Select it, and choose the “Repair” tool
Please let us know what you find so we can pass along accurate information.
This error may come back after repairing and and successfully running Rhino again.
If you find the error comes back, after repairing Rhino, try temporarily disabling McAfee and see if that stops it. You can also configure McAfee to exclude scrubbing the specific files or folders that are being damaged.
You may need to download the Rhino installer and run it if the Repair tool in Control Panel can’t find the MSI.
