My old version of LF95 v5.6 will not install on 64 bit Windows 7

[pw317]

I don't suppose anyone feels sorry for me, but my older v5.6 will not install on W7 with 64 bit processor. The istall fails with error messages about certain modules not being compatible with 64 bit code. I am not using 64 bit, it's just that this laptop(Compact cq60-61dx) has it built in. Since my main Fortran development period is now over, I would rather not buy a brand new license.
A workaround would really be nice here. Does anyone have any good suggestions? I tried copying over the old install directory but that didn't work either for some reason.

Here is something that may work, to the point of your doing useful things with the software. I suggest this approach simply because it has worked with other older packages for Windows NT, not specifically LF56.

From the message "..not compatible with 64 bit code..", it appears likely that you are running Windows7-x64, rather WIndows7-x86. You can easily find out from SystemProperties.

1. Do the installation on a machine with a 32-bit OS. Copy the installed files along with all its subdirectories to the Win64 machine (you probably did this already). Some files that were placed in the Windows system directories may need to be copied over, as well.

2. Set environmental variables PATH, LIB and INCLUDE onn the Win64 machine, and try compiling the DEMO.F90 program.

3. if you have DEP enabled for all applications on Win64, you may have to give exemptions to programs such as 386link.

4. Utilities provided by Lahey in the form of 16-bit programs will not run in Win64. Either replace them by 32 or 64-bit equivalents (e.g., WHICH.EXE) or manage to do without them.

Good luck!
