Downloading and Installing Group Size Calculator
Note: I have migrated to Windows XP Pro, hence can no longer guarantee updates will work on
older Windows platforms. There is nothing I know of that indicates that upgrades developed on
W-XP won't work on W95/98, but
I can no longer test upgrades on these older platforms. As such, I will keep a "legacy" copy
of V1.11 that was built and tested on W95 available for download.
GSC is distributed as a zip file or as a self extracting zip. To download simply click on the
zip download link (for W95/98) or on the
self extracting zip (for W95/98) and save the file on your computer.
Since the next steps will extract a number of files from the zip package, and
after installation you will be able to remove these temporary files, it is
recommended that you create a temporary directory to store the zip file in.
Unzip the file
Using "Start" - "Run" from the Windows menu bar, browse to the temporary
directory and select "setup.exe" (or using Windows Explorer, double click on
the "setup.exe" filename).
The setup wizard will guide you through your installation. It is
recommended that you accept the default locations suggested by the wizard, only
because all combinations of other settings have not been verified.
"GSCalculator" will now appear in your Start-menu.
If you are downloading the W98 version some additional files need to be added. Download
the auxiliary file, open it with WinZip (or other) and place
all the cursor files into the program folder where "gscalculator.exe" is located
(C:/Program Files/GSC/ if you used the default installation).
Give it a spin.
You may now remove your zip file and all the temporary files created in
step 2 above.
A user's manual, an associated example file, and a target scanning backer are
additional recommended files. It is suggested that you create a "C:\Targets" folder
where you can download and save these files, along with future target images you will
create as you actually use the program. The files are:
- If you download the self extracting zip, use either "Start...Run" or Windows
explorer (double click on the file) to execute "gsc_xp.exe" (or "gsc_w98" for W95/98). This will unzip
all the files into "C:\usr\install\temp\gsc".
- Using WinZip, or some similar
package, open "gsc.zip" and extract all the files into the temporary directory.

- Windows 7 (and perhaps Vista) security had issues with the registration file that
GSC created / used. Unfortunately, the extension chosen "in the beginning" was ".reg", which
is now defined exclusively as a registry file. To get around this problem, upgrade to V2.4 of
GSC, which now uses a ".txt" extension to avoid running into security issues with Windows.
- Occasionally during installation Windows reports an error that reads:
An access violation occurred while copying the file"
This means that you already have the file on your system and it is currently in
use by another application (perhaps the installation program itself). If you get this, simply
click "Ignore" and the installation should continue and complete successfully.
- Some users of Windows98 were getting a "Divide by zero" error when entering
bullet hole locations. A previous attempt at fixing the problem was not effective.
I've chased down the real culprit using a Windows98 system and it's now been fixed with
versions V1.3.5 and later. If you have this problem, you will need to re-download the new
