Problem installing latest version

Hi there. Can’t get the latest version build61 to install. Keep getting the following error

c:\wdisplay\clientrawserver.exe
Delete File failed Code 5
Access is denied

I have checked and the file is not read-only.

Hi,
That error usually means that particular program is still running for some reason so close it and try again.

yes, means that program is running
just click on ignore/skip in the installer
