We always say, you can't mix ProjectWise versions on the same machine. So if you upgraded your client because you wanted the latest and greatest version of ProjectWise Explorer 08.11.11.559 and then upgraded your PW Admin to match, if you do not upgrade your database you will get error messages when you try to log into your datasources in PW Admin.
Create Custom database Tables dialog box opens. "Do you want ProjectWise to createtables in database? Enable"Create" button. If you select Cancel you will see Last Error 58198 "cannot login to the data source." Database table verification failed. One or more custom tables are missing.
It has always been a requirement that PW Admin and Server versions to match up. This remains the case with the latest SELECTseries 4 Update. You will either need to downgrade the client on your pc or run PW Admin on the server.
...facing this problem too - should I let PW to create the database tables (by pressing "Create") or not? I don't want to mess the database. Admin works well with another datasource and also on the server. Explorer and Admin are same versions.
Another option is to use a VM on the client and install the alternate version of the ProjectWise Administrator on that VM.
