Error 1330 and Error 272 (or 266) - Digital Signature

Properties ID: 000131
Filed under:
Problem: When installing v5.0 of the eField Guide Viewer application on Windows 2000 or when installing v3.9 or higher on other Windows versions, you may encounter an error related to the digital certificate used to digitally sign the installation files. The error message will be similar to the following:

Error 1330. A file that is required cannot be installed because the cabinet file D: \Help.cab has an invalid digital signature. This may indicate that the cabinet file is corrupt. Error 272 (or error 266) was returned by WinVerifyTrust.

Solution: [This solution for the Gold edition may be easier than following the steps below: First, make a folder on your desktop called ThayerBirding. Then copy the contents of BOTH DVDs into the ThayerBirding folder on your Desktop and then double-click setup.exe to begin the installation. The ONE folder should NOT include sub-folders called Disc 1 and Disc 2 - just copy the entire contents of each disc folder into the new ThayerBirding Desktop folder you create.]

Here is another solution:
Please complete the following steps to fix this error.

1. Open Internet Explorer by right clicking and selecting the “Run as administrator” menu.
2. Select the Tools->Internet Options... menu option
3. Select "Content" tab
4. In the "Certificates" group, click "Certificates..." button
5. Select "Trusted Root Certification Authorities" tab
6. Select "GlobalSign Root CA" from the list (you may need to scroll down. If you do not see it, read the solution below.)
7. In "Certificate intended purposes" group, click "View" button
8. Select "Details" tab
9. Click "Edit Properties..." button
10. Under the "Enable only the following purposes" radio button, check the box for "Code Signing"
11. Click OK
12. Click OK again
13. Click Close
14. Click OK
15. Install Thayer Birding Software's eField Guide Viewer

In Step 6 above, if your computer does not have the GlobalSign root certificate on your computer, do this:

1. Open Internet Explorer
2. Go to www.ThayerBirding.com and click on the Get help tab -> Free Downloads -> GlobalSignRootCertificate. Then save the file to your desktop. Close the Thayer Birding website.
3.Select the Tools->Internet Options... menu option
4. Select "Content" tab
5. In the "Certificates" group, click "Certificates..." button
6. Select "Trusted Root Certification Authorities" tab
7. Click the "Import..." button to start the Certificate Import Wizard
8. Click Next
9. Select the certificate file (GlobalSignRootCertificate.cer) that you downloaded to your desktop in step 1 (please unzip first.)
10. Click Next
11. Make sure "Place all certificates in the following store" is selected
12. Make sure the certificate store is "Trusted Root Certification Authorities"
13. Click Next
14. Click Finish
15. Install Thayer Birding Software's eField Guide Viewer

Here is another solution that should be used only by very experienced computer users:

This morning I stumbled on a solution (which works for Windows Vista) for Error #1330 ==>"file cannot be installed because cabinet file H:\Help.cab has invalid digital signature. This may indicate cabinet file is corrupt. Error 266 was returned by Win Verify Trust" . So I was finally able to install the new DVDs for the Birds of NA Gold edition you sent me! (Great Birding software -- Even better than the previous outstanding versions!)

If anyone else has the same problem I had in trying to install the Gold Edition for Windows Vista, here is the solution that worked for me:
Temporarily set the non-driver signing policy to silently succeed by doing the following steps before installing the Gold edition:
(1) Click on Start
(2) Type regedit in the Start Search box
(3) Right click on regedit.exe
(4) click on Run as Administrator
(5) In the Registry, click on the following key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Non-driver Signing
(6) Take note what the current value is for the Policy Binary Value.
[Mine was 01 and is used here in this example]
(7) Right click on the Policy Binary value and then click on Modify.
(The value will then appear in this format: 0000 01)
(8) Delete 01
(9) Then type 00 so that the current Policy Binary Value in the Registry will now appear as 00
(10) Click OK and close the Registry Editor.
(11) Install Birds of NA Gold Edition
(12) Repeat Steps (1) through (5) to change the Policy Binary Value from 00 back to the original value noted in Step (6)

Finally, you may want to try this:
Copy the contents of the DVD (or for version 5, BOTH DVDs) into ONE folder on your hard drive and then run setup.exe to begin the installation from your hard drive. We think it is easiest to make a folder on your desktop called ThayerBirding so it is easier to find. The setup.exe file will be in this folder. Just double-click on it to start the installation. This will often bypass the digital signature issue.
