Can't Load Any PSU


 

开云体育

Today I tried to load PSU files and always get the same layout which is the stock after install file.

Beta 78 & 79 behave the same.

PSU files I'm trying to load are all correct date and differ considerably when viewed in a text editor.
Files date from two to four years ago.
PSUD uninstalled and Beta 79 installed again.

Note loaded file in bar:



Same cct.

Hi Ian,
?
If you're getting the fullwave solid state diagram as above then PSUD2 is initialising and then failing at the point at which it tries to load the default PSU which is located (typically) at:
?
? ? C:\Users\<myname>\AppData\Roaming\psud\examples\default.psu
?
If this is failing, it's because the default.psu is missing or corrupt (it should give a message), or the 1N4007 rectifier profile has been renamed, removed or corrupted badly. It needs the 1N4007 rectifier for the default PSU to load.
?
A couple of other items:
?
  • I'm using exact same build of Windows 11 as yourself so I don't think there's a Win version issue
  • I would probably shy away from using a text editor to view the PSU files as they are binary; I use HXD which is a great tool for checking binary content. Only mentioning this as if you try and load into a text editor and save again, the file will become "unwell", but I guess you know that anyway. Rectifier files are text/XML so they don't have any problems in this regard
?
?So, how do we fix this? I'd recommend the following steps:
?
  1. Check C:\Users\<myname>\AppData\Roaming\psud\examples and \rectifiers for custom rectifier and files you wish to keep - save them somewhere else
  2. Deinstall PSUD2
  3. Using file explorer, wipe out C:\Users\<myname>\AppData\Roaming\psud
  4. Reinstall PSUD2
?
Hopefully, this will take things back to a stable position, let me know how you get on.
?
Regards,
Duncan

Back up! Thanks.

I also deleted all the PSUD registry data as I had some Beta 3 entries.
NOT recommended for everyone UNLESS you REALLY know what you are doing.
