Hello Mauricio,

1. Yes, it should be compatible, a new version opens a project of an older version and upgrades its format.
2. It is necessary to update ADK, so I think there may be a problem with Xojo 2015 r2, but I'll recheck.

I've done some testing, and Xojo 2015r2.1 works fine with the latest version of V4RB on Windows (I had problems with older versions of Xojo on macOS).

As for OS, Windows 7 definitely should work for Valentina Server and ADK, XP - probably too, but need to recheck.

Thanks, Sergey

I'm waiting for the results of ADK with xojo 2015 r2.

I understand that Valentina Studio Libre can create and edit reports, is Valentina Studio Pro necessary?

The Valentina reporting service, Valentina Studio Pro and ADK sold separately?

Having a Valentina Report 6.2 license, do I apply for a renewal?

Mauricio

Hello Mauricio,

Regarding Xojo 2015r2, it is not available in the archive, so we can't confirm its status.
Xojo 2015r2.1 is confirmed to be working.
Xojo 2015r1 is not working.

Windows 7 is supported for Valentina Server and ADK, but Windows XP is not supported.
Valentina Studio requires Windows 10.

What about the Ubuntu system? Was it upgraded to recent versions? I'm asking because the Valentina Server 13 may require newer versions of the system libraries than were available at 6.2 times.

I understand that Valentina Studio Libre can create and edit reports, is Valentina Studio Pro necessary?

Valentina Studio Pro is necessary for creating and editing reports.
In the Free version, preview and export features are available.

The Valentina reporting service, Valentina Studio Pro and ADK sold separately?

Yes, all products are usually sold separately, although sometimes they are part of promotional bundles, like Omegabundle.

If you are using Valentina Server to generate reports, you don't need an ADK license; the server license is sufficient.
However, Valentina Studio Pro is required in any case.

Having a Valentina Report 6.2 license, do I apply for a renewal?

I've forwarded your questions to Lynn.
Generally, renewals are available within 12 months of the original purchase.
