After reading that 8.01.18 is the most recent version of RDWorks, I attempted to upgrade my 8.01.10 installation using Keith's link at rd-acs.com.
I first tried to remove 8.01.10 from the control panel "Change or remove programs" screen (this is on Windows 10). That threw an error that I cannot now recall, something like being unable to find the uninstaller and removing it from the list. Unfazed, I then ran the uninstaller for 8.01.10 found in C:\RDWorksV8, which seemed to work okay. The icons were removed from my desktop and start menu and C:\RDWorksV8 was cleaned out (except for the uninstaller itself and all of my exported files).
However, when I unzipped the v8.01.18 installer and ran it, I got the following error:
Code: Select all
An error occurred while trying to copy a file: C:\newpr\driver\ftd2xx.h
Click Retry to try again, Ignore to proceed anyway, or Abort to cancel installation.
Abort cancels the installation (duh).
Retry just throws the error again.
If I click Ignore, I get the same error for the next file, which appears to be C:\newpr\driver\dpinst.xml. Then C:\newpr\driver\ftdibus.cat. etc., etc., as far as I can tell through all the files that would normally be installed. DLL files, fonts, executables, .ini files, etc. This advances the progress bar until finally I get a final error message of
Code: Select all
Windows cannot find 'C:\newpr\RDWorksSetUpV8.exe'. Make sure you typed the name correctly, and then try again.
The installer then exits, with nothing having been installed.
Now, the really disturbing part is that when I run the old installer for 8.01.10, I get the exact same error(s).
So I am speculating that the problem is related to my computer and not the actual installer.
As such maybe it is not appropriate to treat this as an RDWorks issue, but I haven't been able to find another instance of such an error (an installer being unable to find its files). So I thought I would ask here. I'm happy to remove this post if it's not relevant to this forum.
C:\newpr doesn't exist on my computer (it's not a hidden folder, either) and it also doesn't seem to be a temporary directory created during the install, since it also doesn't exist while the installer is mid-installation (by which I mean, after clicking Ignore until the progress bar is around half-way).
Does anybody have any ideas for how to resolve this? I've run CCleaner, fully uninstalled v8.01.10 (regretting that a bit now), and restarted several times.
