I have UniDAC 3.7 pro edition installed in Delphi 2010.
Would you tell me how to upgrade to this ver. 4.0 ?
Do I need to uninstall 3.7 then install 4.0? Thanks.

Hello,

You need to download the new version from our website secure*devart*com, uninstall the previous version, and install the new one.

It fails to extract files from unidac40src.exe with password valid for UniDAC 3.7. How we can get new password?

Best regards
Branko

Hello,

You should contact our Sales department at sales*devart*com to get a password to access the new version of the Source Code edition.

I think conditions to do this upgrade is: you must have a qualified UniDAC subscription.
From the email received when I purchase UniDAC, there is a line:
"Note: you have one year UniDAC subscription starting from this date."
If you're out of this period, I think they won't allow you to do upgrade.

Hello,

When we release a new major version of our components, we change the password for the archive with sources. You can get this password from our Sales department.

Was the NexusDB provider removed? It is not in the source and D7 package.

We didn't include NexusDB to the latest UniDAC 4.0.1 by accident. This mistake was caused by the fact that NexusDB doesn't support RAD Studio XE2 yet. We are sorry for the inconvenience. We will fix this problem in the next UniDAC build. Please send your license number to andreyz*devart*com , and I will send you UniDAC 4.0.1 with included NexusDB.
