Has anyone on Server 2012 R2 tried the most recent Quickbooks Desktop Update version R13 released 4 days ago to see if it corrects the error/crashing when going to the Employees screen or anything to do with payroll?  We also have had the same issue after upgrading from our previous R9 version to R11.  Thankfully in a multi-user environment you can do payroll,etc on one of the other workstations that has Quickbooks installed as long as it is an admin.  This is ridiculous that Intuit would drop support for an OS that they initially supported when QBDT 2023 came out! Unacceptable business practices, especially when it comes to software support.  Don't say you support something and then cut that out in the same version. Support it for the life of that version which is the typical 3 year window on Quickbooks versions.
