Sometimes latest versions of the software can cause issues when installed on older devices or devices running an older version of the operating system.

Software makers usually fix these issues but it can take them some time. What you can do in the meantime is to download and install an older version of Inno Setup 6.4.3.

What's new in this version:

- Compiler IDE change: The editor now restores selections on undo and redo
- Inno Setup now includes a new command-line tool, ISSigTool.exe. This tool is designed to sign files using ECDSA P-256 cryptographic signatures. Compil32, ISCC, and ISCmplr use these signatures to verify a number of DLL files before loading them. This is a "technology preview" that is subject to change (e.g., any signatures you create now may have to be recreated when upgrading to the next version).
- Note: ISSigTool.exe does not replace Microsoft's signtool.exe in any way and is in fact not related to Authenticode Code Signing at all
- Fix: Autocomplete support for parameter names in the [Components] and [Dirs] sections was broken since 6.1.1
- Fix: Pascal Scripting support function Extract7ZipArchive which was introduced by 6.4.0 would fail with error 11 on older versions of Windows, at least Windows 8.1 and Windows Server 2016
- Minor tweaks and documentation improvements
