Error 1327 Invalid F Drive When Installing Windows Defender or Adaware

My client has a laptop that hasn't been used much. I went to install Windows Defender, but got an Error 1327, Invalid Drive F. I tried to install Adaware and I got the same message.

Does anyone know how to fix this? I really don't want to go into the registry because I'm a computer tutor, not an IT person. Is there another way?

Thanks.

What drive are you trying to install windows defender on?  Where is the installer located?

kara334Author Commented:
The installer is located on the desktop, like usual.

And the install location set in the installer is the c drive?

Try this to double check your windows directory is correctly set:
1. start>run>type "cmd" and press enter
2. type "set" and press enter

Verify that none of the variables display an F drive

Well, actually I found a solution. I plugged in a flashdrive (an "F" drive), and then I was able to install Windows Defender! So since I came up with the solution on my own, should I delete the question? Or is there something better to do? What should I do with this question?

Kara,

I had the same problem and found a similar answer at

http://www.microsoft.com/athome/security/spyware/software/newsgroups/reader/default.mspx?query=invalid+drive&dg=microsoft.private.security.spyware.install&cat=en_US_F1686F8C-B0B6-48B3-8E05-BA0A64B04E5A&lang=en&cr=US&pt=&catlist=&dglist=&ptlist=&exp=&sloc=en-US

They recommend making a drive with the desired letter available during the installation, either  by mapping a network drive or using the SUBST command (in a command window) to create a virtual drive.  The syntax would be

SUBST [drive:] [path]

where [drive:] is the drive letter that the installer is looking for and [path] is any valid folder path on your system.  For example

SUBST F: C\WINDOWS

To prevent future install problems, however, you will want to fix the environmental variable issue.

I agree justchat_!, but according the discussion at the link posted above, its not environmental, its a bug in the installer itself.  It is interesting however that the drive letter varies.  On my laptop it complained about an invalid drive E:, not F:.  And there was no reference to an E: drive in any environmental settings that I could find.  This was on a fairly new Lenovo laptop running Windows XP Pro.

Ok, maybe both diagnoses are correct.  I think it is a bug in the installer, but I also found a solution under the above discussion link that indicates its also environmental.  But in the registry, not the environment variables.  I'm going to copy the solution posted there to here, with credit to that author:

Hello Rich,

make a RESTORE POINT and try this:

Verify that registry entries do not contain invalid drive letters that
might be causing this error:

Important: The following steps require you to modify the Windows
registry. Modifications to the Windows registry, if not done correctly,
can cause serious problems to a Windows system. Before editing the
registry, see How Do I Back Up Registry Keys on My Computer?

1. Click Start, and then click Run. The Run dialog box opens.
2. In the Open field, type regedit, and then click OK. The Registry
Editor opens.
3. In the Registry Editor, locate the following registry key:


HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell
Folders
4. In the right pane, note the values in the Data column of each
entry. If any value contains a drive that is not correct for your
computer, right-click the entry and select Modify.
5. Type the correct drive letter in the Value data field, and then
click OK. For example, if one of the values is "X:\Documents and
Settings\Administrator", the drive letter should be changed to a valid
drive on the system, such as C:\Documents and Settings\Administrator".
6. Repeat steps 4 and 5 for each entry whose Data value contains an
incorrect drive.
7. Repeat steps 3 through 6 for each of the following registry keys:

*
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User
Shell Folders

* HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

*
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell
Folders

*
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User
Shell Folders

8. Close the Registry Editor and run the installation again.

# If none of the above suggestions apply, this error might be happening
because the installation author has hard-coded a path to a drive letter
that does not exist on the machine. In this situation, you should
contact the software vendor. Your software vendor can follow the
suggestions in the following InstallShield Knowledge Base article to
help determine what is causing the issue within the installation project:

Q107033 ERRDOC: Windows Installer Error 1327.

Keep in mind that the above article is meant for the installation author
that has created the installation. Many of the suggestions do not apply
to consumers trying to install software.

Another suggestion, although not a long-term solution, would be to
create a partition on the local hard drive or map a network drive with
the drive letter that is mentioned in the invalid drive error.
