%CDROM% Is Not Used By WPI

[what3v3r]

for %%i in (C D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist %%i:\file.txt set CDROM=%%i:
echo Found CD-Rom as drive %CDROM%

this part of the batch file, that is run before WPI.hta is executed, correctly identifies my dvd drive.

but it seems that the created variable isnt used by WPI. after i click install in WPI i get the errormessage that "pathtoWPI\applications\programname\setup.exe" cant be found

an example would be: "c:\install\wpi\apps\dotnet\netfxsp1.exe" could not be found blablabla...

"c:\install\wpi\" is the path to the windows post installer that has been copied to the hard disk. instead it should simply be "d:\"

strangely enough, the above script correctly identifies the dvd drive as d:

why isnt that value used by the WPI? i double checked the paths, its all correct. this error happens to all programs i try to install from DVD. so it cant just be a typo or something.

I have seen that happen on machines that have a hidden restore partition. Is that true in your case?

[what3v3r]

not that i know of.

it happened in VMWare and on my home pc. i really dont know what these two have in common that causes this error.

edit: i noticed something else, but i dont know if its related: the cdrom system variable is not available in any other cmd windows i open, only in the one it was created in.

edit2: i now disabled the script that looks for the cdrom drive. instead i created the cdrom variable in the properties dialog of "my computer". the variables that are created there have a sytem wide scope. but it still doesnt work...

SOLUTION FOUND!

Windows Post Install Wizard actually ignores the CDROM variable! i left the cmd script that looks for the drive disabled and looked around in the .js files that the WPI is composed of.

among others, i found this line:

if (FileExists(li[i]+'\\WPI.ico'))

the problem in my case is, that i dont use the wpi.ico file to identify the dvd drive.

after changing the file name to the one i use, everything worked!

i really dont understand why there is a script in the .cmd file to identify the cdrom drive, if that variable isnt even used in the cmd file itself.

<{POST_SNAPBACK}>

some ppl are having trouble with this ,, a solution for some ppl was to replace the

if (FileExists(li[i]+'\\WPI.ico'))

with

if (FileExists(li[i]+'\\WIN51'))

it may fix youre problem but i dunno

[what3v3r]

thx lost soul,

but i already fixed my problem! there should be a way to customize this in the gui. i imagine that many less experienced people have this problem, and no clue how to fix it

no problem m8 i was having the same prob with it not finding the correct drive until i switched it all to find win51 instead of the wpi.ico file, and that fixed it for me of course i had to reroute the addy to point to the win51 file in the root but after that it worked like a charm
