windows - Cannot create files in C:\ProgramData\ even after granting Users group full permission -

we have application tries write access database (.mdb) in c:\programdata\ folder. on computers uac enabled find accessing database fails seems cannot create lock file. seems default (and perhaps due uac) users (including admins) don't have permission write applications folder default.

we thought granting "users" grouping total permissions folder prepare problem, makes no difference. granting "everyone" total command still doesn't help. thing fixes problem seems to move database folder (eg c:\applicationname) not best practice or running application administrator privileges changing shortcut.

how can create normal users can write (and create files) in c:\programdata\ folder? or misusing folder? under impression right place set shared programme info (for users) , many other applications seem have set info there on computer.

update:

i have found clone re-create of database has been set in next folder: c:\users\\appdata\local\virtualstore\programdata\

if delete folder, application performs normally. why folder created? can prevent somehow? because installer not give adequate permissions users grouping on folder in c:\programdata\ ?

could because installer not give adequate permissions users grouping on folder in c:\programdata\ ?

actually, more installer did not have sufficient permissions mess "c:\programdata\" directly. (i thought scenario sounded familiar....)

when microsoft introduced uac needed way older applications go on working, @ to the lowest degree while. came "file , registry virtualization", legacy applications tried access (now-)verboten scheme folders or registry entries redirected own user-specific "virtualized" re-create of resources. wikipedia article on uac describes it:

applications written assumption user running administrator privileges experienced problems in before versions of windows when run limited user accounts, because attempted write machine-wide or scheme directories (such program files) or registry keys (notably hklm).[4] uac attempts alleviate using file , registry virtualization, redirects writes (and subsequent reads) per-user location within user's profile. example, if application attempts write directory such "c:\program files\appname\settings.ini" user not have write permission, write redirected "c:\users\username\appdata\local\virtualstore\program files\appname\settings.ini". redirection feature provided non-elevated 32-bit applications, , if not include manifest requests specific privileges.[13]

if installer requests "run administrator" privileges should able avoid issue.
