so here's MY advice/solution and what i suggest you/people to do:
-for v12 -> go to this thread
[This link Point to another website Only registered and activated users can see links.]
-for v11.6 and even for v12 -> follow these steps i've given before in this order :
1-)OS : Windows XP preferred...Vista maybe, Windows 7 i don't think at all ?! (will be supported by future PDMS version/service packs i guess but not now...),
2-)Graphic card : no pb with your laptop or desktop pc i think...have latest drivers installed if possible,
3-).NET Framework : be sure to have dotnetfx1.1 and 2.0 (and even 3.0 or 3.5 for v12) already installed BEFORE installing the program, it is a MUST and people often forget that (certainly because like you they don't read the Installation manuals)!/,
4-)install PDMS v11.6 or v12 and it's better imo to keep the DEFAULT locations at disk root(C:\AVEVA\Pdms or X:\AVEVA\Pdms where X is your drive letter, e.g on my computer it's H...not in Program Files),
5-)install any add-ons/p@tches/fixes/upgrades if you have any...WHAT does a p@tch/fix do?, they are continually released by AVEVA and provided to their customers to correct/fix some bugs, sorry to sound dumb but really it's those who can't get it the DUMB !...
here's their hierarchy USED : for example PDMS v11.6 is main version,v11.6 SP1=11.6.1 is service pack (major release),126.96.36.199 is fix (corrects minor errors),188.8.131.52 is p@tch in this order...similarly your 184.108.40.206 or 220.127.116.11 is v12 SP0 in fact, not yet v12 SP1, you get it???
...practically, these files will update/REPLACE previous dlls/exe(i.e design/draft/isodraft/admin/etc modules executables...but don't'double-click'on them it's useless, you don't start PDMS like that),
6-)next copy/apply any cr@ck in your dled files if there is (official p@tch is LEGAL/cr@ck by an unknown guy is ILLEGAL..well you see the point) ...so WHAT does a cr@ck do? well, obviously it will CR@CK the dlls/executables not replace them,and create in my case these 4new BATCH files in same directory which are the'real executables': bpm.bat(=Background Process Manager),make.bat
(=Make PDMS New Project...apart from the 3 ProjectS IMPerial/MASter/SAMple supplied directly with PDMS),pdms.bat(=REAL PDMS...if everything's ok you start by double-clicking it or the shortcut desktop, not now!),
7-)install Flexman License Manager now in the same AVEVA directory if not already done(i checked yesterday at AVEVA'support page->Licensing->Flexman : "Flexman 4.1 All AVEVA new products except the Tribon series","Flexman 3.1 &3.1SP1 All AVEVA products before the end of 2008"...which means PDMS v11.4/11.5/11.6 and even your v12.0 issued in july08 use Flxman 3.1 / only PDMS v12 SP4 or SP5 use new Flexman 4.1 which is different and 'much bigger'(7Mb versus 17Mb)...and THAT'S WHY i told u i think i can help!!),...JUST install it, not configure/start it for now...
so, up to now, is that CLEAR ??!!...report if you're ok at this stage.
and then, to be able to help you from this point, i NEED that you post your License file included / and a screenshot showing (exactly) where's your pb during the Installation process, or that attach a copy of them to me via pm...but first of all, you didn't reply so far if 'you're SURE that your License file is valid or not' ??, and plz feedback to confirm you're ok and did well from step 1-) through 7-) too...
