You may have saved your .phm file to a CD-ROM from your old computer.  When you copy files to a recordable CD-ROM, the read-only attribute is typically set for the files on the CD-ROM. When you restore the files from the CD-ROM to the hard disk, the read-only attribute remains set for the files. Therefore, you cannot edit the files unless you manually clear the read-only attribute for the files.

Additionally, if the files remain read-only, the programs that are associated with those files may not start. For example, if you restore a .phm file from a CD-ROM and you do not clear the read-only attribute, Pro Home Manager Personal Edition may not start, and you may receive the following error message:

"File access is denied. You do not have the permission required to access the file."

You can either manually clear the read-only attribute from the restored files, or you can remove the read-only attribute while you copy the files from a CD-ROM.  If you’ve already tried to copy the file, the destination file will have the read-only flag set because the original file did.  Unsetting the read-only doesn't fix anything, because in order to copy the file now you must be able to delete or overwrite the earlier copy in the destination, and the copy is marked read-only.

The solution here is to delete the previously copied file, or at least reset its read-only status as well as that of the original file.

To manually remove the read-only attribute from a file:

1. right-click the file that you want to change, and then click Properties.
2. On the General tab, click to clear the Read Only check box.
3. Click OK.
