Problem:

The following appears when trying to install AutoPIPE or OPIM:

---------------------------
OpenPlant Isometric Manager V8i (select series 6)
---------------------------
“The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2738.”
---------------------------
OK
---------------------------

Solution:

 A google search found the following results:

- This error occurs because the Windows Script Engine is not properly registered.

Avoidance:

Windows Vista, Windows 7

a. In the Start menu, type cmd in the Start Search field.

b. Right-click on cmd in the list of search results and click Run as administrator in the pop-up menu. If Windows needs your permission to continue, click Continue (If you are not logged in as an administrator, you will need to authenticate with an administrator login and password).

c. In the Command Prompt window, enter the following command:

regsvr32 vbscript.dll

d. Press Enter on the keyboard. A message should appear stating: “DllRegisterServer in vbscript.dll succeeded.”
Note: If you see a message with “error code 0x80004005”, the command window was not opened as an administrator.

e. Finally restart the installer

If the above does not work then try the following (reference here):

The alternative solution for a Windows Vista or Windows 7 32bit:

a. Click Start -> All Programs -> Accessories
b.  Right click “Command Promt” and click on “Run as administrator”
c.  Write “reg delete "HKCU\SOFTWARE\Classes\CLSID\{B54F3741-5B07-11CF-A4B0-00AA004A55E8}" /f” and hit Enter
d.  Write “cd %windir%\system32” and hit Enter
e.  Write “regsvr32.exe vbscript.dll” and hit Enter
f.   You should now get a message that says: “DllRegisterServer in vbscript.dll succeeded.”
g.  Click “OK”
