As a matter of interest, where has he got the old installed version installed to? Is it perhaps somewhere non standard?
also, I did see Eloquence in there, might be worth setting the old version to Espeak before starting the installer, just in case.

Replying to briang1:

No; it's just the standard Program Files path.

Also, just in case anyone is wondering why the log says that version 2012.2 is started, that's because a temperary copy was being used at the time when the launcher was run.

Well, Here is how I got the error below. I cleared out a machine of any installed nvda. Installed the previous release version to c:\program files\nvda 2012.1
This means its non standard. When I went through the new installer in the latest beta here is what occured.

I think some modification is going to be needed to the new installer to spot this problem. I still feel that assuming old versions are going to be in the same place is dangerous.

Thanks for testing.

This is odd; I asked this person to type the default installation path into the Run dialog (e.g. C:\Program Files\NVDA), which worked fine. At least we know what that particular error means, though.

Further to that then, If I go into program files with explorer and create a folder called nvda then try the installer again it will work. The extra legend appears saying the install path has changed and most of the old files, but not all are taken from the old folder and the new version is installed to the nvda folder.

Thus It looks to me like nvda installer is seeing the set up in the documents and settings user area as confirmation that an installed version is present, but is not checking if the folder is the right one it expects before its trying to use it in the installer. Thus a simple mod to the installer that says something like if \nvda does not exist, then create it if it finds an installed copy would be all that is needed. I'm off for a lie down.

Should be fixed in changeset,releases,2012.2,5189 or 5caf4b1 (not sure if we have 2012.2 snapshots building).

I think the problem exists in the main branch too, so maybe if its fixed there too, we can test it..

Hi I see the new branch is up so i recreated the old install and it seems to work fine now. Awaiting the original reporter to say if its fixed for them of course.
