This post may help some but many may not fall for this problem. My laptop was dying so had to get a new one. I've had Recorder on SQLServer 2022 Express for a while so I went to install this on the new laptop only to find that SQLServer 2022 Express does not install on computers with an ARM64 processor which I had rather inadvertendly purchased. I eventually found some installers at https://github.com/jimm98y/MSSQLEXPRESS-M1-Install from a bloke who had knobbled the official Microsoft installers to make it work and it did. My next problem came from my next mistake. I had been on Recorder 6.30 and thought I still had to install 6.28 first and then upgrade to 6.30. The 6.28 install worked fine but the upgrade kept failing due to lack of user permissions despite this using the sa user which I did the installation with. I think this may be an ARM64 issue from googling. I then noticed websites saying SQLServer 2025 Express did install on ARM64 PCs so went this route and the Microsoft installer does work but does also moan about the processor. But the Recorder upgrade still failed. I finally noticed that there is a full standalone installer for 6.30 so didn't need to do the upgrades at all and have done that and now have a full working Recorder again. I'll worry about upgrades another day.
