I can't work out what I'm doing wrong, but it seems I am doing something wrong and keep getting this error

 

 

Any hints on what I need to change to get the toolkit working again?

"Used by another process" indicates that the SNG file is still open by the toolkit or some other program. You can try re-opening the toolkit and see if that SNG file is then able to be accessed.

Confirm you don't have the 'Z://...' file path open somewhere.  Sometimes a reboot is necessary to close open files.  If you still can't get it then PM EOF project files.

Thanks - Firekorn pointed out my error - was trying to use the same XML for lead and rhythm, copied the xml and it had no issues when trying to create the package.

Is it your AV blocking Toolkit from normal work we need to indicate this somehow... but for now add toolkit to the trusted apps or just to test - disable it for a while :)

damn

if it's the case.

if no - delete sng file and try again, but it should work with shared resources? maybe try disable  caching or work locally

Toolkit nowdays won't let you use 2 same xml files so I think you're using pretty old build.

The screen capture says he's running 2.6.1.0 (rev db5e4d59), which is the latest version that the forum points to.

@@raynebc, then it's broken I guess, I'd like to have auto-tests done, by someone who know something about testing :D

Yeah - update was done minutes before I first started getting the issue.  

  

I've previously had no problems with this track (having said that - I last built a package from these project files in 2014), importing the 1 xml file twice and just changing one of them to Lead in the import dialogue, (it's created in EoF as Rhythm), so wasn't really considering that as the issue.

 

Making a copy of the XML (even named PART REAL_GUITAR_RS2 - Copy.xml) , allowed the package to be built without problems.
