[wix-users] Wix MBA: Prompt for source of container: WixAttachedContainer

[Farrukh Waheed]

Hi,
Upon launching setup from Control Panel -> Programs & Features, my
installer (MBA) failed with following errors:
[0AB4:096C][2015-09-15T14:52:06]w341: *Prompt for source of container:*
WixAttachedContainer, path: E:\VA\My.Setup.exe
[0AB4:096C][2015-09-15T14:52:06]e054: Failed to resolve source for file:
E:\VA\My.Setup.exe, error: 0x80070002.
[0AB4:096C][2015-09-15T14:52:06]e000: Error 0x80070002: Failed while
prompting for source (original path 'E:\VA\My.Setup.exe').
[0AB4:096C][2015-09-15T14:52:06]e311: Failed to acquire container:
WixAttachedContainer to working path:
C:\Users\My\AppData\Local\Temp\{993269ac-9279-46f9-a14d-29db116d9f1e}\AA0C8038D5F9D76891056E8FA562328025092F68,
error: 0x80070002.

I guess, this was happening in CachePackageBegin event. so I tried to
read WixAttachedContainer as string variable, but it popups this error:
---------------------------
Exception
---------------------------
BootstrapperCore:Element not found. (Exception from HRESULT: 0x80070490)
---------------------------

*Question: How can I resolve WixAttachedContainer and raise the dialog to
get user's input for "Prompt for source of container"??*

Thanks a bunch
Farrukh
