Topic: browser tries to download one .exe, other .exe runs OK

{previously posted as a reply to similar topic in coding & scripting corner, but no replies - getting desparate}
I have 2 windows .exe files in the same folder on my 2 servers. For several years, they both worked. Now ONE of the .EXE's tries to download onto the user's machine. I am running Apache 2.2.16 & Windows 7-64 on 1 machine & Apache 2.2.15 & Win 7-32 on the other (both have the problem). Server .conf files are identical, except for folder names (since the 32-bit machine is on a domain). No errors in the logs (return code 200 on my Form POST request). Permissions for the 2 files are identical. Programs use the SAME DLLs, both written in C++ (without any objects).

After searching the literature and finding no help, I recompiled the failing program (MS VC 2008) and it still fails. The other one still runs properly. Here is my http.conf entry:
<Directory "E:/DJs Documents/public_html/cgi-bin">
AllowOverride
Options FollowSymLinks Includes ExecCGI
IndexIgnore ..
<Limit GET POST OPTIONS PROPFIND>
Order allow,deny
Allow from all
</Limit>
<LimitExcept GET POST OPTIONS PROPFIND>
Order deny,allow
Deny from all
</LimitExcept>
</Directory>

and I have:
ScriptAlias /cgi-bin/ "E:/DJs Documents/public_html/cgi-bin/"

Any suggestions greatly appreciated.

Do you send a header in both files?

[DocDJ]

Yes, I send the "content-type" line in both. I did some further investigation and turned internal debug in the program. It is failing in trying to open a file for read+write (mode "a+"). The file does not exist, so must be created & I get errno=13 (defined as EACCES). The error slso shows up in the windows application logs in the Event Viewer. It appears that Windows 7 server apps trying to write files on the server, require some additional permissions, but I haven't figured out where/how to set them.

Any tips greatly appreciated.

It would be great to have the source code to reproduce that.
