Hi, Someone said that a way to run Win 2.xx applications (like Excel & Page Maker) without restarting windows in real mode was to run win 3.0 in real mode FROM win 3.0 running in enhanced mode, sounds great to me. Windows will start up and then I get a DOS share violation error and I have to abort. Any suggestions ?? Perhaps PIF settings for the window that runs win /r. ANy other ways to run win 2.0 apps from win 3.0 Thanx, chris@seas.gwu.edu P.S. Thanx for all the responses to my last question :-)

The problem is a SHARE violation caused when trying to execute Windows 3.0 from within itself. This is not caused by Windows but by the DOS SHARE utility which is required when using DOS 4.0 extended partitions. The SHARE violation is caused because Windows keeps its own files open during execution to allow it swap in and out code which is not kept in memory. The solutions are as follows: (1) run without SHARE. If you are not using extended partitions this will not cause you any problem. (2) Reinstall the 2.xx applications with a copy of the Run-time Windows which came with Excel. This will allow you to execute the Win 2.xx apps in full screen mode under Windows 3.0 in Enhanced mode. (3) Install two copies of Windows 3.0 in two directories. One for use in real mode only, the other for enhanced mode. I suggest running the Windows 3.0 Install procedure from a DOS window, so that it installs without seeing any expanded or extended memory. (This I have not tried.) (4) The best solution. Get the upgrades for you software. I have the same problem you do as I use a PS/2 55sx with 4MB and a single partition 60MB hard disk. I am currently using suggestion two, while waiting to complete suggestion four. The reason that suggestions two and three require that the software run as a full screen app is that otherwise you lose your mouse control for the earlier version of Windows. BTW, Microsoft recommends using only Windows 3.0 and manually exiting and reentering every time you need to switch between Real Mode and Extended Mode applications. They suggest using the Clipboard file format to store your data when you need to transfer data between Real and Extended Mode applications. Hope this helps. - Jeff (jaltman@ccmail.sunysb.edu)
