All Reflection Windows-Based Products version 13.0 through 14.x


When attempting a workstation installation of a Reflection product from the product CD or the downloaded product files, you may receive the following error: "Incorrect command line parameters version..." This technical note provides suggestions for troubleshooting this setup error.


Try the following troubleshooting suggestions to resolve the most common causes of this error.
  • Confirm the existence of your Temp folder and TMP definition.
  • Manually initiate the Reflection installation.

Confirm the existence of your Temp folder and TMP definition.

Setup will automatically try to write to the Windows temporary file (Temp) folder as defined by the Windows TMP environment variable. Typically, the Temp folder is created automatically by the operating system. If it has been deleted, problems can occur during setup.

Note: An environment variable named "TEMP" may be defined. This variable is NOT used by Reflection Setup or by the MSI installer service. Only the "TMP" environment variable is used.

Follow the steps below to confirm the existence of your Temp folder and TMP environmental variable definition:

  1. First, check for a Temp folder definition. Open a Command Prompt (DOS) and type: echo %TMP%.

If you receive a folder path in response (for example, C:\TEMP), then the TMP environment variable is properly defined.

If not, add a definition for the Temp folder (for example, SET TMP=C:\TEMP).

In Windows XP: Control Panel > System > Advanced tab > Environment Variables button

In Windows 2000: Control Panel > System > Environment

You may need to restart your computer to make this definition active.

  1. Next, verify that the Temp folder exists by typing dir %TMP% at the Command Prompt.

If you see a list of files, the temp folder does exist. Continue with step 3.

If the response says "File Not Found," create a Temp folder using either the mkdir command or the Windows Explorer.

  1. Finally, verify that the Temp folder is writable. While still at the Command Prompt, type: echo this is a test > %TMP%\test.txt.

If you receive the response "Access is denied," the folder is read-only. If this is the case, change the TMP environment definition to point to a writable folder (see step 1 above).

If a Test.txt file is created in your Temp folder, then the file is writable.

Manually initiate the Reflection installation.

Manually run Setup.exe from the \Reflection folder on the Reflection product CD, the downloaded product files, or from the root directory of an Administrative Install.

If you still receive the error, try installing Reflection by right-clicking the .MSI file and selecting Install. The .MSI file name varies slightly depending on whether you are using the Reflection Evaluator or the Reflection product CD.

From the Reflection Evaluator

In the \Reflection folder, select the MSI file for the product you are evaluating. The table below lists the .MSI files associated with each of the Reflection 14.0 products:

Reflection Product
.Msi File Name
Reflection for HP with NS/VT
Reflection Suite for the Multi-Host Enterprise, Standard Edition
Reflection Suite for the Multi-Host Enterprise, Professional Edition
Reflection for IBM
Reflection X
Reflection Suite for X
Reflection for UNIX and OpenVMS
Reflection for Secure IT: Windows Client

From the Reflection product CD

In the \Reflection folder, select the .MSI file for your product\. The .MSI file name are the same as the names listed in the table above.

For example, on the Reflection X 14.0 product CD, the .MSI file name for Reflection X is RX140ilc.msi.
