(based on ESXI five.5, machine ver 10). we received the following error once tried to edit its properties to feature a new interface card.
Editing VM settings failing with the error: you cannot use the vSphere consumer to edit the settings of virtual machines of version ten or higher.

I had the choice to downgrade it victimization v-converter consumer, however, Time was extremely short as the whole network was down and the recent physical machine was additionally out of order, therefore I used the following hack to feature the interface quickly and create it online.
Turn OFF the desired Guest,
Remove the guest from the inventory (Right-click -> take away from inventory)
Browse your ESXi datastore wherever guest files area unit placed,
Now transfer the .vmx file from your situation wherever your guest files area unit placed (Example guest’s name. Vmx file)
Open it in any text editor (Example pad of paper PLUS+),
Change the subsequent …
virtualHW.version = “10” to virtualHW.version = “8”
As shown within the image below

Save this file and transfer back to original location.
Add the guest back to your inventory by right clicking the vmx file and choosing “Add to inventory”
Now try and edit the guest properties, and now you’ll be ready to screw.
There were other workarounds too however therein specific scenario, I found this methodology the foremost fastest and in particular, it worked well 🙂
After I initially left a comment I appear to have clicked on the -Notify me when new comments are added- checkbox and now every time a comment is added I recieve four emails with the same comment. Perhaps there is an easy method you can remove me from that service? Thanks! Perry Carny Zacherie
