what have tried far

• at tools --> extensions , updates have tried de-install , re-install extensions. when click on menu item "extensions , updates" "object reference not set" exception?? can't try option.
  • i have deinstalled visual studio 2015 , reinstalled it. no effect.
  • i have done suggested in https://connect.microsoft.com/visualstudio/feedback/details/1123745/setsite-failed-for-package-microsoft-visualstudio-editor-implementation-editorpackage @ 13-2-2015 @ 16:49. no effect. in fact entire exact same folder structure , files (at quick glance) gets copied after starting visual studio 2015 again.

so... suggestions out there?

updates question

first update

i tried load project and... wrong. can't load bunch of packages like: "csharppackage, integrationpackage, migrationpackage, fileindicatorpackage, etc..." , solution explorer blank! going on?

second update

this how programs , features like:

third update

i have uninstalled , removed as dared.

• removed in appdata\roaming\microsoft\visualstudio\14.0
• removed in appdata\local\visualstudio\14.0
• uninstalled visual studio 2015 via programs , features (above screenshot)
• removed visual studio secondary installer folder in program files folder altogether
• removed has visual studio 14.0 program files

i don't want mess visual studio 2013 installation. vs2015 still can't load packages above! if has more information programs can uninstalled above screenshot happy.

fourth update

steps taken (updated update 3)

• removed in appdata\roaming\microsoft\visualstudio\14.0
• removed in appdata\local\visualstudio\14.0
• remove concerning visual studio 14.0 programdata
• uninstalled visual studio 2015 via programs , features (above screenshot)
• did article says: https://support.microsoft.com/nl-nl/kb/3016536
• removed visual studio secondary installer folder in program files folder altogether
• removed has visual studio 14.0 program files basically. left on uninstalling in programs , features.
• uninstall microsoft visual c++ redistributable (x86) - 14.0.xxx also
• uninstalled xamarin stuff also
• hope didn't forget anything, bottomline totally rid of visual studio 2015 related.
• reinstall visual studio 2015 rtm , should work now. have install 3rd party stuff again, atleast works!

i have visual studio 2012, 2013 , 2015 installed on machine. after installing visual studio 2013 update 5, started getting "package did not load correctly" error in vs 2013.

all did working follow step:

1. close instances of visual studio
2. delete in folder c:\users\%username%\appdata\local\microsoft\visualstudio\12.0\componentmodelcache
3. restart visual studio

though have not tried 2015, believe should solve problem too. visual studio 2015, 12.0 should changed 14.0

update

instead of deleting in folder (as suggested step 2 above), more safer rename folder , allow visual studio create new one. sometimes, might have copy somethings on old folder.

i hope further all.
