Every so often when updating NVDA, I intermittently receive an error,due to nvda_slave.exe not exiting. Doing a manual closing of nvda_slave.exe from the processes tab of the windows task manager in Windows XP SP3, then pressing the "Retry" button succeeds in the update.

I've no idea how NVDA closes nvda_slave.exe before exiting, but this error only occurs every so often. Here's a fragment of the log:
ERROR - RPC process 4316 (nvda_slave.exe) (00:03:58):
main.main:
Task failed, try again
Traceback (most recent call last):
File "nvda_slave.pyw", line 29, in main
File "installer.pyc", line 348, in install
File "installer.pyc", line 311, in tryRemoveFile
RetriableFailure: File C:\Program Files\NVDA\nvda_slave.exe could not be removed
ERROR - gui.installerGui.doInstall (00:03:59):
Failed to execute installer
Traceback (most recent call last):
File "gui\installerGui.pyc", line 32, in doInstall
RetriableFailure

Obviously this is a minor bug, but I thought it worth reporting anyway as I couldn't find an existing ticket for this issue.

This is very odd. nvda_slave should never be running after NVDA exits. Particularly in Windows XP, it's not used for much at all.

Do you see it in Task Manager when just normally using NVDA?

Replying to jteh:

No. In normal day-to-day use, I never see this executable's entry in the task manager. Keep in mind that I don't regularly look, but I don't think I ever saw it in use.

@jcsteh You found the reported issue particularly odd initially, and the original author of this ticket, although now out-of-reach, did respond in #3890 (comment). Thoughts?

Closing as works for me, as we haven't had any report of this in several years and I can't reproduce it.
