A Windows Update in late November / early December 2015 broke the
capability of BusinessVision to export reports and forms to a PDF
file. This also affected BusinessVision's ability to email forms,
since these are first saved by BusinessVision as a PDF.
You will get Error 999 "Operation not yet implemented"
The cause of this is Windows Update KB3102429.
Here is how to uninstall that update and
prevent it from reinstalling.
PLEASE NOTE that I will be using an example
for illustration purposes an update different from KB3102429, as I
have already uninstalled that update from my computer.
In Windows, go to Control Panel, Windows
In the lower-left corner, click on Installed
Updates. The following screen shot shows a partial list.
Scroll down until you reach the Microsoft Windows section. Update
KB3102429 shouild appear in the list.
Please note that the following list was taken from my
own computer AFTER I had already uninstalled the update!
Right-click on KB3102429 and select
PLEASE NOTE: In the following example, a different
update is selected for illustration purposes, since I have already
uninstalled update KB3102429.
After confirming and going through the uninstall procedure, you
will be advised that you will need to restart your computer. Don't
do that yet.
Instead, click the "back arrow" near the top of the screen to go
back to the main Windows Update screen.
Then click on Change Settings.
Change the Important Updates setting to one of "Download
updates..." or "Check for updates...". Then click OK at the bottom
of the screen.
One more thing needs to be done: You will need to tell Windows to
never try to reinstall that update.
First though, you should restart your computer.
When your computer is back up, go into Control Panel, Windows
Update, and click "Check for Updates". Windows will go looking for
updates and hopefully you will see update KB3102429 on the list.
If it is, right-click on it and select "Hide Update".
Once again, PLEASE NOTE that I am using as an example an update
other than KB3102429.
Once you have done this, you can set your Windows Update Settings
back to automatic if you wish. I advised that you set them otherwise
in an easrlier step in case you were not able to have the KB3102429
update reappear in your list of Recommended Updates.
