PicBasic Pro and Windows 7

[Darrel Taylor]

On 64-bit systems, programs are not allowed direct access to the printer port that was used for the old EPIC programmers.
And any attempt to access it results in errors or lock-ups.

The 4.40 installer should have recognized the 64-bit windows, and disabled the printer port access. But it can be overridden by old .ini files or the port menu.

First, uninstall previous versions of the melabs programmer software.
Delete the folder and any contents if it still remains. C:\Program Files (x86)\melabs Programmer

Delete the application data folder.
C:\Users\Your Name\AppData\Local\VirtualStore\Program Files (x86)\melabs Programmer

Then re-install meProg 4.40.
Select ONLY the U2 programmer when the installer asks.

After installing, start meprog using the (melabs programmer shortcut) first.
Don't run it from MicroCode Studio until it has been opened from the shortcut.
Then close meprog, and try it from MCS.

And make sure you have the U2 programmer plugged in before starting the program.
