Restoring FactoryTalk View Machine Edition (ViewME) Applications from an Application Archive (.apa) file is typically a straight forward endeavor.
One exception is when you're restoring a pre-6.1 application on a 64bit OS using FactoryTalk View versions 6.1 through 9.0, and I cover those issues in the below articles:
- Easy Way To Migrate FactoryTalk View Projects To 64 bit
- How to Migrate FactoryTalk View Projects to 64 bit
Another exception (and the one this article in about) is when you're trying to restore FactoryTalk View Machine Edition (ViewME) applications that include User and Group security created on a different PC in versions 4 through 7.
The reason for this is, versions 4 through 7 of ViewME uses the local FacotryTalk Directory (FTD) to store Users and Groups, and you can only have one local FTD active on your PC at any given time.
And by default, when you restore a ViewME application the local FTD for that application (which contains its Users and Groups) is not restored because it would orvewright your existing local FactoryTalk Directory.
So to be sure you don't lose your current local Directory, while still being able to restore and edit version 4-7 applications from other PCs, follow the below steps:
Step 1) To insure you don't lose the security settings for your current applications, the first step is to backup ALL of the View Machine Edition AND View Site Edition Local Applications on your PC.
You do so using the Application Manager, and you can find a step-by-step procedure in my article here:
Step 2) Now that all your local FactoryTalk View applications have been backed up, run the Application Manager again:
Step 4) Now select Restore application, and click on Next:
Important: Only do this is you have already backed up your applications as directed in Step 1
If you forget to restore the FTD with a version 4-7 project that has security, you'll likely see Security ID's in place of Users and Groups in the Runtime Security settings.
This indicates the current local FactoryTalk Directory is not the same as the one used with the open application.
