HydroCAD® Stormwater Modeling - Since 1986


This documents applies to HydroCAD 6.0 only.  Later versions of HydroCAD use a different installation program in which this problem does not occur.

Missing "temp" Folder

If the setup program requests an additional disk or is unable to find certain files, you may have a problem with the "temp" folder on your computer.  This folder is designated by Windows for the storage of temporary files, such as the HydroCAD installation files.

Work-around:  Click the "browse" button (in the setup error screen) and navigate to the folder c:\windows\temp\$INFTool.tmp. This should allow the setup program to complete normally.  If the $INFTool.tmp folder doesn't exist (or the installation still reports missing files), you have a missing or incorrect temporary folder.

To check the temp folder:   Go to a command prompt (DOS prompt) and type set.  You should see a line beginning with "temp=" such as this:  temp=c:\windows\temp  If the temp line is missing (or it points to a non-existent folder) you must edit your autoexec.bat file as described below.

Permanent fix:  Change the autoexec.bat file to identify the correct temporary folder:
1) Select Start/Run and type sysedit
2) Find the window for autoexec.bat and locate any existing line that begins with "set temp=".
3) Modify the line (or add a new one) so that it points to a valid temporary folder.  In most cases the line will read set temp=c:\windows\temp
4) Close the windows, being careful to save your changes.
5) Reboot the computer and repeat the installation procedure.

Other Issues

In some cases the TEMP setting may be ignored, causing a different temporary location to be used.  If this is a protected folder (such as \windows\system32) the temporary files may be missing or misnamed.  (Windows 2000 has been observed to rename the files, placing an additional letter at the start of each file name.)

Solution:  Change the set temp= line as described above, so that it points to a "temp" folder on your boot drive, such as c:\windows\temp.  (Setting temp to other drives may cause the setting to be ignored.)
