Summary
This article provides the causes and solutions for this error.Symptoms
The folder path contains an invalid character.Cause
This error can occur for the following reasons:
- On Windows 95, 98, or ME, your user profile contains an invalid character, such as a slash "/".
- Your CD-ROM drive uses a real mode (16-bit) driver.
Resolution
- User Profile Contains an Invalid Character
- On Windows 95, 98, or ME, your user profile may contain an invalid character. Determine if your user profile contains an invalid character by navigating to C:\Windows\Profiles\Your Profile, where Your Profile is the name of your user profile, such as James Jones. If your profile contains characters, such as "/", for example, James/Jones, your profile may be damaged. Windows should not allow you to create a user name with invalid characters.
- There are two possible fixes: You can turn off user profiles and then run the installation or you can install the software under a different user profile. Turning off user profiles installs the software for all users of the computer. Installing the software under a different profile may install the software for only that profile.
- To turn off user profiles, follow these steps:
b. Double-click Passwords.
c. Click the User Profiles tab.
d. Select All users of this computer use the same preferences and desktop settings.
f. Restart your computer if prompted to do so.
g. Run the installation. This installs the software for all users.
h. To turn user profiles on again, repeat steps 1-3 and select Users can customize their preferences and desktop settings.
i. Restart your computer if prompted to do so.
6. For more information on disabling and deleting user profiles, see Microsoft Knowledge Base article 156826 How to Disable and Delete User Profiles.
7. Your CD-ROM drive uses a real mode (16-bit) driver.
8. To run your installation, your CD-ROM may require a 32-bit driver. To determine if your CD-ROM is a using real mode 16-bit driver, follow these steps:
a. Select Start > Control Panel > System or Start > Control Panel > Performance and Maintenance > System.
b. Select the Hardware tab.
c. Click Device Manager.
d. Locate the CD-ROM branch in the device tree. If the CD-ROM branch does not exist, you are using a real-mode CD-ROM driver.
Windows NT/2000
a. Select Start > Settings > Control Panel > System.
b. Select the Hardware tab.
c. Click the Device Manager tab.
d. Locate the CD-ROM branch in the device tree. If the CDROM branch does not exist, you are using a real-mode CD-ROM driver.
Windows 95/98/ME
a. Right-click My Computer.
b. Click Properties.
c. Click the Performance tab. If you see a message stating that some drives use MS-DOS compatibility, you may be using a real mode (16-bit) CD-ROM driver.
a. The easiest solution is to copy all the installation files to your computer and run them from your hard drive rather than the CD-ROM. To do this:
-
Create a folder on your hard drive (e.g., your Desktop) by right-clicking and selecting New Folder.
-
Double-click My Computer.
-
Double-click your CD-ROM drive.
-
Press Ctrl + A or select Edit > Select All to select all the installation files.
-
Drag and drop all the files into the folder you created in step 1.
- Right-click each file and select Properties to make sure it is not Read-only. If it is, deselect the Read-only check box.
- Run the installation by double-clicking setup.exe (or similar file, e.g., installer.exe).
