Problem Installing Windows 11 on Fusion 10

[SnakeGirl]

i have successfully installed Windows 11 on Fusion 13 (more than once) & the process was very straightforward.

However, when i attempt the Windows 11 installation on Fusion 10 using the same drag & drop method w/.iso file downloaded from Microsoft, i get an error message of "This PC can't run Windows 11", "This PC doesn't meet the minimum system requirements to install this version of Windows.  For more information, visit https://aka.ms/WindowsSysReq".   i have checked these requirements & i believe i've adjusted the settings accordingly on my new Windows 11 VM w/respect to Processor, RAM, & Storage, but i'm not clear on how to make sure TPM 2.0 is set up/enabled correctly on a VMware virtual machine.  (In Fusion 13, all these settings were automatically taken care of prior to installation & i didn't have to check or change any settings at all.)

Any ideas or suggestions?  What am i missing?

Fusion 10 doesn't support Windows 11 AFAIK.

What is AFAIK?

AFAIK = As Far As I Know

You may be able to get Windows 11 to work on Fusion 10, but it's a royal pain the backside. You are far better off running Windows 11 on Fusion 13, as it was built to support it. You will find installation will be much easier as well.

See the following article originally written for Fusion 12, but you might be able to use it to install Windows 11 on older versions of Fusion:

Some things to be aware of when reading this article.

In the discussion in the article about the Trusted Platform Module requirement for Windows, ignore the the instructions to use the "Software feature" - Fusion 10 does not have that capability. It's also a half-baked feature that will get you in more trouble than it's worth in Fusion 12 where it is available. 

Did I say that you really should be running Windows 11 on Fusion 13?

You must encrypt the virtual machine before adding the Trusted Platform Module device to the virtual machine. Adding the TPM device is done through the VM's settings - see the in-product help or the Using VMware Fusion documentation available on-line. The big issue here is that in Fusion 10l the entire VM is encrypted - even the virtual disks. You must remember the password or else you lose the entire VM. You will also see a performance decrease in the VM due to Fusion's encryption overhead.

If you do not encrypt the VM and configure the TPM device, you must hack the Windows registry keys in order to get Windows 11 to ignore the requirements for the TPM device and Secure Boot. That's discussed in the VMware article.

But i just want to see if it is even possible to get it running at all on Fusion 10, even if it is a pain in the neck.  That is the question.  (Just as i was able to get macOS Ventura running on Fusion 10, i'd like to see what happens in the case of Windows 11.)

Update:  

Many thanks to @Technogeezer , who pointed me in the right direction yet again!  After reviewing the article(s) you referred me to, i decided to attempt installation bypassing the TPM 2.0 requirements entirely & followed the instructions to 'hack the Windows registry keys in order to get Windows 11 to ignore the requirements for the TPM device and Secure Boot' discussed in the VMware article.  This way i could simply skip & not have to deal w/the whole encryption/TPM issue which i never knew prior to reading the article was even an option.  i actually thought this would be the quickest & simplest thing to try 1st & it was not even a royal pain in the backside at all since the instructions given were excellent.

Much to my pleasant surprise, this method was successful, & i was able to create the Windows 11 VM on Fusion 10 quite expeditiously in just as simple & straightforward a manner as i had previously been able to do on Fusion 13 without any special instructions.

As always, thank you so much, @Technogeezer !!!
