BarTender 9.21 error Follow


Hi All:


We use BarTender 9.30.2725.2652  --  the computer installed it on crashed, and I was able to get all our labels that we'd already had sorted for us off the bad drive and I copied over all the Seagull folder to the new drive.

But when I click one of our .BWT files to print a label, I now get an error message:

"the application has failed to start because its side-by-side configuration is incorrect....."

Do I have to reinstall Bartender on the new computer?  I'm largely ignorant of IT matters but I'm unfortunately (at this time)all we got!

I would recommend trying to a complete manual removal and reinstall of BarTender. Do note the version of BarTender you are using is no longer supported and only compatible with Windows 7/Server 2008 R2 and below operating systems. For further support, you probably want to look into getting an upgraded version of BarTender.

Instructions for manual remove/reinstall of BarTender:

  1. Go to the Windows Control Panel->Programs/Features->find Bartender right click to uninstall it->follow the installer prompts to uninstall and deactivate BarTender.
  2. Manually remove the following folders:
    1. C:\Program Files (x86)\Seagull
    2. C:\ProgramData\Seagull
    3. C:\Users\<specific user>\AppData\Roaming\Seagull
    4. C:\Users\<specific user>\AppData\Local\Seagull
  3. Remove the following registry keys:
    1. HKEY_CURRENT_USER\Software\Seagull Scientific
    2. HKEY_LOCAL_MACHINE\SOFTWARE\Seagull Scientific
    3. HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Seagull Scientific
  4. Open the Windows Services to confirm all the BarTender related services are removed.
  5. Reboot computer.
