I've installed TASM 5 on DOSBox and it works just fine. I can't remember exactly how I did it, but I don't remember running into many problems.

Thanks for the info.

I haven't ruled out that I am making some silly error, that no one else has done =/ Because, I have not found so much info on my particular error.

I will keep plugging.

From what I've read, this error can occur if you try to install TASM to the root of the drive. Be sure you are installing to a subdirectory (such as C:\TASM5\).

Here is what I just tried:
1. Dosbox installed, and launches and appears to function as expected, so I will assume this part is correct (in C:\dosbox\ directory}
2. copied the tasm installer into the C:\dropbox\ directory...as well) The C:\dosbox directory has the following:
\Dosbox-0.74
\users
\tasm

3. I created a folder named "tasm5" in my C:\ directory
4. I mounted as d c:\dosbox\
5. I mounted e c:\tasm5\
6. move to d:, browse to tasm, and type install.exe.
7. I select the source of the installer d: (c:\dosbox\tasm)
8. and the destination of the installation e: (c:\tasm5)
--"too many subdirectories: Press esc"

After I escape, I can observe that within the folder i created, there is a new folder created by the installer named "tasm5", so inside of c:\tasm5\tasm5", 5 other new directories are created (all empty): bin, doc, examples, include, and lib.

Might be a factor...

but I am using Windows 7, 64-bit professional.

Not sure if it is or not. I have had the same problems with 64-bit Mac OS X 10.8

Trying a different installer, this one has three clear disks. So, since I can't figure out how to "insert disk 2" (and 3, subsequently), I just copied all the files into a single directory, so the installer could always find them.

Ultimately, I get to the same place: "too many subdirectories."

I am keeping a record of this, and my steps, in the hope that either a. someone can help me, or b. this can help someone else in the future.

Your mountings are unconventional, and remember that under typical conditions the installer was originally used to install from a floppy drive to a hard drive. I suspect your c:\dosbox folder has multiple subdirectories that a floppy would not, and that is the source of the installer's complaint.

mount a c:\dosbox\tasm -t floppy
mount c c:\tasm5
a:
install

Take the default install directory of C:\TASM, or change it to C:\TASM5, but do NOT change it to C:\

FYI, you can hold Alt-F12 for unlocked cycles during the installation process to make it go faster.

Thanks..

tried it, but got the same error. Really starting to think it's a windows pro 64-bit error.

did exactly as suggested...installing from a, to both default c:\tasm, and tried also c:\tasm5

always same error message: "too many subdirectories"

Doesn't seem likely to be a 64bit Windows problem; I'd expect a lot more reports of problems with file and folder operations if that was the case. Make sure DOSBox has access rights to create / write / delete files and subfolders on the folder you're mounting as the C drive. Could be that your installation files are bad or incomplete.

try installing to c:\ and not c:\tasm5

copy all of the files from all three disks to a single directory on your hard disk. mount that directory as your root directory.
then run install.exe.
it will ask "enter the source drive to use", select "C"
it will ask "enter the source path", select "\"
then start the installation.
you'll end up with a "tasm" directory under the directory where you copied the files.
I still use TASM in DOSBox for my 16-bit needs.

thanks for all the help!

finally got it to work. =)

These are the steps I used, though not sure if they were required or not.
1. got a different installer, that had borland assembler on 3 (floppy) disks.
2. I copied the contents of the three disks to one folder.
3. then did as recommended, used that one folder as a mounted a: drive.
4. then, what appeared to be necessary, was to mount TO c:\
then it worked.

thanks for the help. =)
