Over 99% of installation failures of our software are caused by
one of:
- Incomplete or corrupt downloads of setup files (most likely)
- Overly "intrusive" antivirus/antimalware software
(quite likely)
- Insufficient hard disk space (common)
- Installation of other software not complete yet (common)
- Presence of temporary files from other software installation
(rare)
All our executable files are digitally signed, which makes it
possible to confirm the integrity of the file. If you right-click
the setup file and select Properties, you should be able to verify
that it has a valid digital signature. If it hasn't, then this is
likely the result of an interrupted download. In this case, we
advise to re-download and verify that the new download has a
different file size. If the issue issue persists, as often indicated
by the size remaining unchanged, and by a lack of digital signature,
this probably means that you are re-downloading the same partial or corrupt
file from your local browser cache, or from an ISP cache, in which
case you can try and press Ctrl to force a cache flush when
re-downloading.
If you establish that the setup application has a valid digital
signature, and the installation still fails, we advise to
temporarily turn off any antivirus/antimalware software that you may be running,
and retry the installation. If the antivirus/antimalware software
asks you for permission to proceed with an installation step (e.g.
copying a file, writing to the registry, etc.), and you do not
authorize such step, the installation will be incomplete and the
software will most likely not work as intended.
If the installation still fails, this could indicate a low disk
space on either the destination partition, or the partition holding
the temporary files (Windows "Temp" directory). As a rule of thumb,
you should make sure that the partitions that are used have at least
100 MB of disk space, plus three times the size of the setup file
itself.
Because our software uses standard Windows installer (MSI)
functionality, which is also used by other installers, if a
previous installation of another program has not completed yet,
any attempt to install new software may trigger the request to
complete the previous installation. In this case, make sure to
either complete any pending installations of other software, or
uninstall such software, if you do not wish to complete said
installations. The other software may require a reboot to
complete this installation or uninstallation process.
As a last step, if you verified all of the previous steps and
you performed a reboot, and installation still fails, you may
want to try emptying the temporary directory, to make sure that temporary
files which may have been left over by other installations have
been removed. There is a known issue with some versions of
InstallShield setup packages, which, by not removing certain
temporary files, prevent the installation of other programs. To
solve this, delete the contents of the "Temp" directory used by
the installer. To access this directory type "%temp%" in the path
field of an Explorer window. This points to a directory like
"C:\Users\username\AppData\Local\Temp", "C:\Documents and
Settings\username\Local Settings\Temp", "C:\Windows\Temp",
"C:\WinNT\Temp", "C:\Temp", or similar. Some
temporary files may be in use, in which case the deletion may not
completely succeed, but, unless the procedure which created these
temporary files is still in progress (or if it required a reboot
which has not yet been performed), it is usually safe to delete
the entire contents of these directories.
The majority of files in Amiga Forever are Amiga files, which
do not work outside of the emulation, and which it would not be
meaningful to process by Windows antivirus software. You may
therefore want not to grant "antivirus" software access to
the Amiga files or to the
Amiga Explorer namespace because letting
an application designed to scan for malicious Windows code monitor
Amiga files which were never even meant to be run on Windows has a big
performance impact, but little practical use.
