Initially, I had 1.4.1.1009 installed.
I installed one of the later versions of forms player 1.5.4.xxxx (and nothing worked)
The splash always said 1.4.1.1009.
In 'add remove programs' there were two forms player entries.
I uninstalled both.
I tried to install version 1.4.1.1009 from your web site by going through downloads etc...
All I got was a page with 'Page Not Found' at the top.

I am moving this issue to Installation as requested
Today
I tried installing 1.4.3.1040 and I imediately get the result screen that asks if the version number displayed is correct and that if it is missing then I have had installation problems.
I tried 1.5.4.1030 and I got the installation dialog boxes however after installation the version information was blank.
formsPlayer is being downloaded and installed. Please wait.
...
formsPlayer version:
The software was installed in C:\Program Files\x-port.net Ltd\formsPlayer Community Edition\
These were the only files there.
atl70.dll
license.rtf
mfc70.dll
mfc70u.dll
msvcp70.dll
msvcr70.dll
readme.rtf
I looked in the registry for classid 4D0ABA11-C5F0-4478-991A-375C4B648F58 and could not find it under CLSID
I did find it under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Code Store Database\Distribution Units

Frank, have you looked at this thread that looks like it deals with the same issues as you have?
