Hello Everyone (Rich/Dave),

Recently, our system gurus installed the new version 5.10 (build 080512) in all of our PCs. The old version 5.0 were all uninstalled for some reasons... For previous version (4.5), the v.5.0 can be installed without uninstalling the older v.4.5.

My concern is, we are in the midst of our project schedule and the client requirement is only v.5.0, but, most of our guys have already opened the stress files using the new v.5.1.

Can we convert the newer versions (5.1) back to the older versions (5.0) by making a neutral file?

Also, can we install both version on the same PC without uninstalling either version?

Thanks in Advance.
