This is the release history since I took over development of the Clean Installer:

1.6.22.0

* Recognize default installation paths for 64-bit and UC, thanks to abluescarab at MTS.

1.6.21.0

* Access registry in read-only mode when trying to get display name. Hopefully, this will solve the recent spate of problems with installing to EA Games\\Teleport.
* Try to find name and description of mods from Catalog Description and Version Information records.

1.6.20.0

* Add checkbox to remove furniture from lot.
* Better error handling. Do not display "succesfully installed" message if files did not install correctly.
* Install CC into Downloads folder with an extension of .package, when installing lots into a non-default Teleport folder with an extension of .Sims2Tmp. This mimics the behavior when installing lots into the default location.
* Resolve a bug where occupied lots with CC were installed incorrectly. Please note that occupied lots are NOT considered to be safe.

1.6.19.0

* Find save game through HKEY_CURRENT_USER, rather than HKEY_LOCAL_MACHINE. This should ensure that files are installed to your save game, rather than the administrator's.

1.6.18.0

* Recognize incomplete BodyShop projects (ie, those without a Binary Index).
* Mark incomplete BodyShop projects in light blue.
* Add LotCatalog to browsable folders.
* Recognize more behavior mods.
* Recognize UI mods.
* Recognize BodyShop packages with no Texture Overlay XML, as long as they have Mesh Overlay XML.
* Duplicate hacks are now marked in Pink, rather than Red.

Note: This version highlights (in light blue) BodyShop projects which do not have a Binary Index. These are almost always incomplete BodyShop projects which will not show up in your game. However, there are some default replacements which will be incorrectly flagged, such as Phaenoh_DEFAULT_SocialBunniesRedefined. Therefore, you should be sure to check the flagged packages before removing. Requested by fanseelamb.

1.6.17.0

* Use HTML encoding for file paths, to avoid problems with &, <, >, and ".
* Give an indication if no update to the program is available.
* Fix bug where Young Adult and Elder clothing were not properly categorized.

1.6.16.0

* Use HMTL encoding for embedded file names, to avoid problems with special characters: &, <, >, and ".

1.6.15.0
* Do not install item on multi-install form if the checkbox is unchecked.

1.6.14.0
* Fix a bug in the mipmap processing which could cause an infinite loop.
* Resolve a registry-access problem with the save game directory on MACs.
* Fix problems with INI processing which resulted in multiple INI files.
* Add a new SaveGamePath line to the S2PCI.ini file, to allow user control over the install directory.
* If S2PCI cannot find the save game folder, ask user to specify the path and then write that path to the S2PCI.ini file.
* Remove the auto-update of the package list, since this file is no longer being actively updated.

1.6.13.0
* Display game version used to create lots.

1.6.12.0
* Recognize official Maxis recolors.
* Recognize pets.
* Add JPG records to available images.

1.6.10.0
* Resolve problem which prevents the installation of Sims2Packs into a non-default directory, when the Sims2Pack contains lots, families, or sims.
* Recognize meshes.
* Recognize category mods; ie, mods which just recategorize existing hair, clothing, etc. Category mods include un/hiders, catalog changes, age conversions, etc.
* Recognize hair color and clothing, even when they link to existing textures.
* Recognize clothing, even if it has multiple property sets.
* Better descriptions for clothing: more compact, more complete, include Young Adult age and Pregnant and Outerwear categories.

1.6.9.0
* No more .package.package extension when installing Sims2Pack into non-default directory.

1.6.8.0
