Has anything changed on your system recently; e.g. something uninstalled, system restore, updates, etc.? I can't think of anything we've changed lately that should cause this.

Also, does this happen when you restart NVDA with control+alt+n or only when you restart your system?

Hello.
One of my friends with windows vista is also having this problem with 2014.3.
When we try to run nvda with control+alt+n, or by clicking the desc top icon we get the error mentioned above.
However if we use the run command and we type nvda the program starts fine. So I assume something is wrong with the short cut key or the desk top icon.

The shortcut key/desktop icon launches slightly differently so that the shortcut key will restart NVDA while it is already running.

In [a741e72]:

In Windows Vista, a spurious "Entry Point Not Found" dialog is no longer displayed in several cases such as when starting NVDA from the Desktop shortcut or via the shortcut key.

Py2exe was bundling mpr.dll, which is a Windows dll that differs across different versions of Windows. ShellExecute was loading our copy of this dll instead of the appropriate dll for the system.
This has now been added to the list of system dlls that we explicitly exclude in setup.py.

It'd be great if Windows Vista users running next could confirm that this is fixed in the 10 September next snapshot when it is available.

Technical: As to why we're seeing this now when we weren't before, I guess a Windows Update on our build machine must have updated mpr.dll and the new version of mpr.dll is incompatible with Windows Vista.

Hello.
Thanks for fixing it.
Since the fix won't be available until 2014.4, how can I temporarily fix this for my friend?
Can we download the appropriate mpr.dll and replace it with the one that doesn't work?
Thanks
Nikos

Exit that copy of NVDA and simply delete mpr.dll from the NVDA program directory.

Actually, it just occurred to me that I need to make the installer remove this for updates.

Remove mpr.dll when updating, as it will have been installed by an older version.

Replying to jteh:

Actually, wait until the 11 September snapshot. The 10 September snapshot fixes the issue for new installs, but not for updates; the installer needs to remove the previously installed file in the latter case.
