Hello, Yesterday I posted the troubles I had when trying to install MM 2.2.3 in Win95. They are caused by the setup routine failing to identify Win95 as a 32-bit OS. This results in the request for installation of the win32s library (something you must avoid if running in Win95, otherwise the results are disastrous). Failing to install the win32s library (stored in Disk 5) results in the termination of the install program. Therefore, running setup under Win95 is useless, at least with my version of Mathematica. This is a bit weird since Mathematica's install program recognized Windows versions > 3; in fact, the wolf2.mst script (which is in compressed format in Disk 1) has an entry for the Chicago ver of Windows (the pre-release of Win95). The problem may well be within the Win95 version I have installed, which happens to be the latest revision (1111).
the version of Mathematica I have. This is a bit weird since the installation process in MM 2.2.3 should, in fact, be able to detect the memorable 'Chicago' version of Windows (the pre-release Win95). In fact, the script in the file wolf2.mst (which appears compressed in Disk 1) has an entry which should be able to identify Windows version > 3. The problem may therefore be in the way the setup routine 'queries' Windows for the version number, or on what my installed version returns as version ID (which is the latest revision, 1111; I've anyway heard this also happens with the OEM Win95 vesrion). After some thought, I found a way around this (the dirty way; hey you guys at Wolfram, any better ideas?). First, make a diskcopy of your MM Disk 1 AND ONLY WORK WITH THIS COPY. Also, have handy the old DOS 6.2X setup disk, and retrieve from it the EXPAND program. Now, copy the file wolf2.ms_ from your backup disk of MM Disk 1 into your temp directory in your HD, and EXPAND it by issuing the command EXPAND WOLF2.MS_ WOLF2.MST This de-compresses the wolf2 script file. Now edit this file. Go to line 177. Between this line and line 215 inclusive (which should read EXITCODE%=EXITSUCCESS) there are a bunch of conditional loops which are processed by the setup routine to 'query' for the Windows version, and decide if installing win32s or not, even if installing MM at all). DELETE ANYTHING BETWEEN LINES 177 and 215. INSERT IN THAT SECTION THE FOLLOWING: EXITCODE%=EXITSUCCESS WIN32ENABLED%=1 DEST$ = WINDRIVE$ + ":\WNMATH22" GOTO OPTION This sets the flag for win32s to 1 (it is here) without querying, sets the default installation directory for MM and jumps to the OPTION subroutine, from where the install process continues. Save the file as WOLF2.MS_ It is important that you save the file with the extension MS_ and not MST. This does not affect the processing of the file (that is, adding the final T) even if the file is de-compressed. The expand procedure would say the file is not compressed, but that is totally transparent for you from the setup routine. The extra T will nevertheless be added. Now copy this 'tweaked' wolf2.ms_ file to your backup copy of MM Disk 1. Run Win95, and install from this backup floppy. Now, the first query you should be getting from the setup routine is if you want the default install or a custom one; the request for installing win32s is GONE. Proceed then as usual. Win95 users: recall that you should update the TCP/IP protocol file, by downloading it from Wolfram's WWW or FTP site. Hope this helps. Ed
