@jesfknkrys I haven't installed the cumulative update (KB5058499) yet so it must be something else that makes HyperSpin work. But it's good to know HyperSpin still works with that installed too. It has been a rollercoaster ride for HyperSpin 1.5 over the past few months & it also goes down to what manufactrer of PC you have whether or not HyperSpin 1.5 works or not as you know mine was working well before yours, a few weeks at least. Thanks for all info you shared with the community. I do reccomend people do clean all there cache files & temp files though if still not working & do a re-start then a shutdown before trying again though. It made my PC with TPM work as at first HyperSpin didn't work with all updates applied until I did that. I have 2 PC's 1 with TPM & 1 without TPM. It means I installed Windows 11 PRO on 1 PC with supported hardware & 1 PC without supported hardware. They both work with HyperSpin 1.5 Thanks to all !!

@jesfknkrys another thing i used rufus to create bootable usb installation & don't know if this helped but i installed windows 11 pro on a unsupported pc so removed tpm & unsupported 4gb to install. I forgot i used these settings when installing on a supported windows 11 pro pc but enabled tpm after all updates applied & was 11gb supported also so I don't know if that had an affect on my supported windows 11 pc as don't want to install again with rufus & go through the hassle. I used the same rufus installation on both unsupported pc & supported pc for windows 11 pro but just forgot i removed those 2 windows 11 requirements when i installed on supported windows 11 pro pc. Both the unsupported pc & supported pc HyperSpin is working so is that what made my Windows 11 pro make HyperSpin work? I can't say. Try installing windows 11 pro without removing those 2 requirements & installing all updates then if that doesn't work try installing removing those 2 requirements & all updates. But remember exclude entire drive from defender & install HyperSpin requirements software ect. that it needs to run as windows 11 you have to enable something as it's turned off by default. I'll pm you when i get back home around 1pm uk time wednesday

@jesfknkrys i still have my windows 11 install file do you want it ?

HyperSpin Original works fine for me on windows 11 pro all updates installed also. HyperSpin Original is on a separate drive with windows defender excluded from it entirely also controlled folder access is off but don't know if it makes a difference with it on or not. I did do 1 other thing I used AVG TUNE UP & cleaned all junk including everything apart from my download folder if it wasn't highlighted i changed it to full including windows set up files & old back ups ect. everything cleaned browser cookies you name it all full clean just my download folder ignored that's it. All drivers fully updated & net 2.0 activated again as sometimes windows 11 turns it off as i found out that was off when i started RocketLauncher UI so if RocketLauncher UI only says can't update then you know all is OK. Hope this helps people !

@Dime333 I just installed KB5050411 & HyperSpin is still working on Windows 11 Pro. All updates are installed nothing blocked. My HyperSpin Drive is not on C:Drive it's on E:Drive with it excluded entirely from Windows Defender but also I have controlled folder access turned off so not sure if that has any effect or not as not tried it with controlled folder access turned on. Windows 11 Pro deleted some HyperSpin files so I had to put the missing files back, if you can try HyperSpin on a Windows 10 to make sure it's working as that's how I knew Windows 11 Pro deleted some files but before I ran HyperSpin on Windows 11 Pro I excluded the E:Drive from Windows defender first. I hope this helps

Nothing is blocked, all updates are installed, I just moved everything to a different drive, not the operating system drive, replaced files windows 11 removed, then excluded that drive from windows defender & everything now works on windows 11 pro.

@jesfknkrys I have these updates installed & no further updates it says & nothing blocked. it shows KB5055523 is installed but windows 11 deleted some files when trying to run HyperSpin which I only found out when trying to run again on windows 10. I put the files back & put drive back into windows 11 then excluded the drive entirely from windows defender. HyperSpin is now working in windows 11 PRO so might be different on HOME editions. Here's my list of update history https://postimg.cc/XXZ7dRFB

Is your windows 11 all up to date & HyperSpin working ?

I don't see this update in my list but it says up to date when i click on check for updates. (KB5053598) when did above update come out ?

I have all the updates installed on windows 11 pro & just found out that when you run HyperSpin the first time with all the updates it deletes some files as I put in my windows 10 pc & it wouldn't work so replaced the files & added an exclusion in windows 11 pro & wow HyperSpin satrted working again. Whats installed am I missing any that causes the problems as exluded entire drive & HyperSpin Works. https://postimg.cc/G8kwWf7z
