Sage 100

Just upgraded a stand alone Sage 100 Standard from 2015 to 2016. During the migration I received a file not accessible error and crash. Now when I try to get into Sage 2016 I get the Sage 100 ERP box with 4503 Error #12: File does not exist (or already exists). Any ideas? There is no Instlock file in the Home directory.

When this has happened to me in the past I simply uninstall/reinstall or copy my ""clean"" mas90 backup I took before the migration. I suspect you migrated system files such that it deletes them without checking that they were migrated (paperless office does this too). I expect you could also install a new 2016 on another computer and copy the missing files from it though I'd call that a last resort. additionally I would check the migrated folder (the mas90 you copied from) for permissions, correct size, and also check the new install for permissions.
