There are two different problems:
- One of them is the error I get when I install EV client (as described above). I have seen that I also get the message "Welcome to the Symantec Enterprise Vault Outlook Add-In Upgrade Setup" (Note: Upgrade). Even if I completely remove it before. And even following Rob's instructions. But I have seen that it only happens in 2 or 3 PCs, those that I have been using to test the second problem (the other one). I think that after install, remove and reinstall several client versions there's something left that Windows 7 thinks that the client is already installed and is trying to do and upgrade (and saying that Outlook 2010 is not supported).
- I'm more worried about the other problem: Users prompted for username/password when opening an archived email. Most of the users are still using Windows XP/Office 2003 with no problems. Some weeks ago we started with a Windows 7/Office 2010 pilot project, installing that in about 25 PCs. Then problems arrived. Some users has no problems and can open archive emails well and some others (like me) not. Some examples:
- Fisrt time I installed W7/Office 2010 on my PC I had no problems. EV client was working fine (10.0.1 and 10.0.2). One day I had to reinstall my PC from scratch. After that, I started to be prompted for username/password.
- There are 2 users working fine with their W7 PCs. If one of them change to the other user PC and start a session there, Outlook prompts him for login/password when opening an archived email. Coming back to his PC he can work fine again.
- One user started to use a new PC with W7 a couple of weeks ago. No problems. Suddenly, a few days later (without having doing any changes on the PC) started to be prompted for login/password.
No rules for this behaviour.
I also check and test all the scenarios in the technote suggested by ZeRoC00l. Negative. Everything there seems to be fine.
All the PCs are joined ti a domain.
Best regards.
