startup error: Vendor configuration file

PrusaSlicer won't start. Give this error: 

"Vendor configuration file PrusaResearch contains the following presets with names used by other vendors: 0.05mm ULTRADETAIL, 0.05mm ........" and then a huge list.

What to do?

Cheers!

RE: startup error: Vendor configuration file

Sounds like you have a corrupt file.  I hope you backed up all your customised profiles using File>Export>Config Bundle ?  Although its always possible the configuration snapshots might work.

You could manually go into the files listed in the error and try and edit things but thats not an easy way and you would have to know exactly what you are doing. 

Probably the easiest way is to start clean.  That means removing (deleting or better yet renaming) ALL the prusa slicer folders.  Not just the program ones but the configuration data folders too as thats where you problem probably is.  Then reinstall.  Run through the wizard to get all the system profiles back (if you did in the first place). 

You can then restore your custom profiles from the config bundle.  Or if you renamed the folders the config snapshots should be in there somewhere so you might be able to copy those over and use to restore what you had.  I'd be a bit wary of those though as its always possible the snapshot could have been taken with the dodgy config data (low possibility of that though).

First, thanks for the quick, thorough answer. I am truly grateful!

Second, reinstall and lose all my customizations and filament settings!?!?  (This pisses me off.  Of course, that's not your fault.)

If the programs needs backups, why don't they happen automatically? Like every time I start. Baffled and angry.

Cheers,

Tom

Which ones? I found C:\Program Files\Prusa3D\PrusaSlicer\resources but I don't know which files need to be renamed.

Thanks for your help!

Wait, I found C:\Program Files\Prusa3D\PrusaSlicer\resources\profiles\PrusaResearch.ini.

Are there others I should keep?

You said "all the PrusaSlicer files". Sorry. I am in a bit of a panic.

RE: startup error: Vendor configuration file

Depends on what OS you are using.  Normally if you start PS you can go to Help>Configuration folder and it will show you where all the configurations are kept.  That doesn't help you if you cant start the software though.

For example on my Win 10 machine the profiles are stored in C:\Users\********\AppData\Roaming\PrusaSlicer.   Theres is a folder in Program files but its an older one from PS 2.2.

In the current roaming folder there are several folders.  The Vendor folder has the basic system PrusaSystem.ini and the Creality one in there for me.  Thats because I have Prusa and Creality profiles installed from using the wizard to add printers.  It may be that just the prusasystem.ini has been corrupted but you cant tell.

In my folder there are also several other folders of interest.  First of all theres a folder called Snapshots.  This contains other folders that are dated whenever the software does a configuration update from Prusa.  Basically when theres a new version configuration update like a new filament added or an update to the basic print profiles it takes a snapshot and saves them in there.  So don't be angry as PS does do backups.  You definitely want to back those up.  As even if you end up doing a complete reinstall you can copy them back.  Actually you could just copy those files from the snapshot back over the current ones and see if it starts up.   In normal circumstances you can manually do a configuration snapshot from the menu and restore any in the snapshots folder once PS does start.  So you can do a clean reinstall once the folders are renamed, run through the wizard once  to get the basic system profiles then close the software.  Copy the snapshot folder from your backup to the newly installed and empty one and then start PS again.  It should then have access to the snapshots you copied over.  Then use the Configuration>Configuration Snapshot from the menu to restore to one of the snapshots.

You mentioned your customised profiles.  Well in there are also folders called Filament, Print, Printer, Physical_printer.  They contain your customised profiles.  They are saved as individual ini files so you can import them in individually if needed.  So you haven't lost everything if you can find those folders.

However get into the habit of doing periodic manual backups by using File>Export>Export Config Bundle (or the one that includes physical printers).  A config bundle doesnt contain any system profiles but will contain ALL of your customised print, filament and printer profiles.  They are an easy way to transfer your configuration from machine to machine or to do disaster recovery.  When a bundle in imported it just restores them all in one go.  This method predates the Configuration Snapshot option which was added by Prusa as it was in the original Slic3r.

Uninstall and reinstall gives same error!

I used the PrusaSlicer standalone installer to uninstall the program. Then reinstalled. But I got the same error. I uninstalled and reinstalled again, but I got the same error. I reinstalled to a different folder. I got the same error.

I used a program called IOBit Uninstaller to analyze the PrusaSlicer uninstall. It said there were 30 registry entries and 15 files left after the uninstall. I used that program to delete the files and entries left over from the uninstallation. I reinstalled, and that worked.

I copied back my original PrusaResearch.ini to see if I got back all my nozzle and filament settings from the last 18 months. No effect. All my filament settings are gone.

Thanks for your kind help @Neophyl.

Yes an uninstall does not remove any configuration/profile data.  Afterall if you lost that when you update you would be equally pissed off.  As your issue is with a corrupted profile file though then re-installing wont do anything.  Thats why I said you have to back up and then remove all the files.  It would have been betetr to rename the files/folders your uninstaller found rather than deleting them.  Thats why you dont have anything left.  Its a nuclear option.

The prusaresearch.ini does NOT contain any customised settings.  It only contains system ones.  As such saving it is pointless as it can always be installed on a clean install  See if you can find any sort of backup, did windows create any snapshots during its updates or anything similar  that you can restore?  

Do you ever use the save project option when slicing ?  That is another habit to get into.  Always save a project for everything you slice.  A saved project also saves the print, filament and printer settings used when it was saved.  You can load in a saved 3mf project file and then manually save the profiles used back into your saved list.  While no where near as good as a saved config bundle it can be handy.  Any gcode generated from Prusa Slicer will also have the saved settings stored at the end of it.  You can use File>Import>Import Config and load in the settings from any saved gcode that was used to generate it.  Not as good as a project but potentially useful too.

That is very useful and good to know, thank you!
