Thank you for using VMware Workstation 15.5 pro.
Did you copy the virtual machines files from esxi server directly ? Did you try to use ovf tools or download VM from WMware Workstation 15 Pro connected to esxi server?
if possible, Could you pls help to share more information(such as vmx file,vmware.log etc.).
Yes, the virtual machines were directly copied from ESXi. It worked well for the past three years, until last week I updated the ESXi to version 6.7 (they were in 6.5) and the vm's to version 14.
I didn't get to try it with ovf tools. I didn't try to connect WMware Workstation 15 Pro to ESXi because it is a production environment.
What details do you need from the vmx file, vmware.log?
Can someone please test a copy of a virtual machine directly from ESXi 6.7 to Workstation 15 Pro, to see if the error is reproduced?
This issue couldn't be reproduced in our environment. we copied a win2012R2 VM directly from ESXi 6.7u3 server(15160138) and the VM can boot as normally.
BTW, copy the virtual machines files from esxi server directly is not recommended by VMware official. there may be some configurations will most likely lead to a compatibility problem.
Thank you very much for the test.
During this week I will try to perform additional tests and then I will share the results or conclusions.
I inform that the problem no longer exists.
Thanks for the support and for the information provided.
The problem was happening because I was using a copy of the VMs, obtained through the backup copy of Veeam, which are incremental copies and contained the transition from VMware ESXi version 6.5 to version 6.7.
I tested a new copy of the VMs, but this time full, without containing the transition from the ESXi version. And in these conditions the problem does not occur!
