Can version 3.5 co-exist with version 4.0?

[Toedwy]

Gentlemen,

Our company has tons of HOURS of 3.5 development.  We attempted to install 4.0 on with an already 3.5, it appears you cannot run 3.5 Editor at all.

Is this true or am I missing something?

We would hate to jump off the cliff and install 4.0 and hope that our 3.5 sequences work flawlessly.

Thanks for any info.

Are you using the TestStand Version Selector to switch between 3.5 and 4.0? I got my upgrade to 3.5 from 2.0 the day before 4.0 was released and haven't done anything in 3.5 but I've been able to switch between 2.0 and 4.0 with no problems.

Hi Matt,

Dennis is correct, and the knowledgebase here has more information on setting the Active TestStand version.  You may also find this link useful. Hope it helps.

Thank you,

I overlooked the "TestStand Version Selector"

Works great, thanks again for your time,
