Hello,
First, sure the issue is from VMware Tools.
Then, in order to install the VMware Tools you have to attach a CD\DVD to this VM. once done i guess the Install VMware Tools will be allowed.
Otherwise and if you have another normal VM with CD\DVD, mount the VMware Tools installation to it, go to the mounted drive copy the content and share it with the primary VM. On your VM start a normal installation, once succeeded your problem should be solved.
If my reply was helpful, I kindly ask you to like it and mark it as a solution
Regards,
