Hello!
This issue was reported to Esri Support and a defect was logged to further investigate the cause and potential solution. Our Development teams have been actively working to get a fix for this issue over the last week. At this point, we are in early stage of testing fix for this issue and the current plan is to issue a general patch for the affected products.
Esri does not recommend workarounds that involve modifying the PATH environment variable or deleting msvcr90.dll from folders listed in the PATH, as doing either can negatively impact any application reliant on the DLL. If the application referenced in the PATH environment variable is nonessential, uninstalling it may provide a safe workaround for the issue. Removing unnecessary items from Internet Explorer’s list of addons may also help.
This knowledge base article provides further detail on this issue.
Thank you everyone for providing feedback to us, and we apologize for any inconvenience that this issue might have caused on your workflow.
Regards,
Prasanta.
