About STEDwin: STEDwin is the smart editor to simplify working with Purdue or PennDOT* STABL programs. I am pleased to announce the latest version of STEDwin, v2.90, with improved help files which runs under Windows 11 (32-bit or 64-bit), Windows 10, Windows XP, Windows 7, and Windows 8. STEDwin allows on-screen data entry and modification similar to a spreadsheet. STEDwin itself performs no stability analysis but allows the user to concentrate on the engineering aspects of slope stability analysis while it takes care of writing the data files in the format expected by the slope stability analysis program.
STEDwin then creates high quality graphics from the STABL output files. The graphics can be printed in color or black and white to any printer supported by Windows, saved as .BMP files, or exported as AutoCAD compatible .DXF files. STEDwin supports the latest version PCSTABL7, PCSTABL6 (all versions released in 1999), PCSTABL4, STABL4M, PCSTABL5, STABL5M, STABL6H, and both PennDOT versions PASTABLE and PASTABLM. *However, PCSTABL4 and the PennDOT versions PASTABLM and PASTABLE are 16-bit programs and will not run under Windows 7,8, or 10.

STEDwin upgrades for Windows 7, 8, 8.1, and 10: If you have STEDwin 2.84 or older, then an upgrade to the latest version of STEDwin is required because Windows 7,8, and 10 will not allow execution of the older 16-bit STABL programs. If you have installed your current STEDwin program onto PCs with these newer Windows versions you will encounter a problem where STEDwin indicates that it cannot find the output files after selecting "Run Analysis". I have recompiled the STABL5M.exe and STAB6H.exe FORTRAN source code and named the new executable files as "STABL5M2.exe" and "STABL6H2.exe" (i.e., they end with "2" to indicate 32-bit) so that they will work on these newer Windows operating systems. The cost to upgrade your existing STEDwin "site licenses" to Windows 7,8,and 10 is $149, and each existing "additional user" license upgrade cost is $25. To add more users, the cost is $50 for each additional user license.

How to get Purdue University's PCSTABL program: Purdue University announced a new version of STABL6 in March 1999. An update was released in January 2000. The new STABL6 includes geosynthetic reinforcements and soil nailing. Note that Purdue has also released a Windows version of STABL6, but only the DOS version is compatible with STEDwin. In November 2002, Purdue released their latest program, PCSTABL7, which is not the same as GSTABL7. STEDwin 2.82 and later is fully compatible with Purdue's PCSTABL7 program!

How to get PennDOT PASTABL programs: PennDOT no longer distributes its PASTABLM and PASTABLE software. However, it is public domain and the programs and user guide can be downloaded here. Important note: The PennDOT programs are 16-bit and will not run on 64-bit versions of Windows 7, 8, 8.1, or 10.
