Attempted load of LMS 7.7.3r1375965195 on XP.
.Steps taken start with dot (.)
[comments in sq. brackets]

.Loaded XPpro-sp2 Dell installation on a newly formatted disk
.Ran all the updates to get me to sp3 with no more updates required.
.Installed LMS 7.7.3 with no errors.
[LMS would not start from control panel. 
Similar to other reports.
No log was created and Diagnostics reports 'Possible Software conflict'. 
Disabled firewall - no joy.
Single user and no UAC in XP.
Assumed it was XP 'protecting' me with firewall and 'malicious software' restrictions.
Note that there was no suplimental anti-virus or other 'protection' installed.]
.Reformatted.
.Reloaded XPsp2.
.DID NOT UPDATE.
.Attempted to load LMS - errored with req. that I install Msi3.1 from MS.
[Installation did complete.]
.Same results.
[Assumed possible corruption due to old Msi.]
.Reformatted.
.Reinstalled XPsp2.
.Installed Msi3.1 (KB893803-v2-x86).
.Installed LMS with no errors.
[LSM would STILL not start. Same 'Possible software conflict found.']
.Loaded ProcExplorer to see what process was failing.
[Noted that SqueezeSvr would load while the tray icon blinked then would unload after failing.]
.Ran SqueezeSvr from 'Run' menu. 
[Noted there was some message - flash and gone.]
.Ran SqueezeSvr from cmd window and got the following message:
[--quote--]
C:\Program Files\Squeezebox\server>SqueezeSvr.exe
The following CPAN modules were found but cannot work with Logitech Media Server
:
  Audio::Scan:

To fix this problem you have several options:
1. Install the latest version of the module(s) using CPAN: sudo cpan Some::Modul
e
2. Update the module's package using apt-get, yum, etc.
3. Run the .tar.gz version of Logitech Media Server which includes all required
CPAN modules.

Undefined subroutine &main::main called at slimserver.pl line 101.

[It appears that the windows compiled executable is missing include files. (Audio::Scan).]

Additional note:
I unloaded Squeezbox7.7.3 and installed & configured v7.6.1.
All was well with the world - until it noted a 'new' version was available and installed 7.7.3r1375965195.
I am back at the beginning.
Aurgh.

If you wish additional diagnostics, let me know.
